Pain in the legs can occur as a result of conditions that affect bones, joints, muscles, tendons, ligaments, blood vessels, nerves, or skin. Leg pain can occur in the foot, ankle, knee, behind the knee, thigh, down the back of the leg, or in any part of the leg. It can occur at night, while lying down, or while running or exercising, depending upon the cause. Depending on the cause, leg pain can occur in one leg only or in both legs. Typically, the leg pain is a result of tissue inflammation that is caused by injury or disease. Either injury or chronic disease can cause inflammation to any of the tissues of the leg and lead to leg pain. Since the leg contains a number of different structures and tissue types, a wide variety of conditions and injuries can cause leg pain.
Depending on the cause of the pain, other symptoms, like
- aching, or
- a tingling sensation, may accompany leg pain.
Diabetic neuropathy (nerve damage from diabetes) is a common cause of tingling, burning, and numbness in the legs that can at times be painful. For diagnostic and therapeutic purposes, it is important to differentiate the exact type and location of any pain in the legs. Peripheral artery disease can cause claudication, or pain that occurs in the legs usually when walking or exercising. Blood clots (deep vein thrombosis) can be another cause of leg pain. Pain in the knee and ankle joints of the leg is common with the arthritis conditions. The pain of sciatica (from disc disease of the spine) may radiate down the leg and is another common cause of leg pain.
Other causes of leg pain
- Bacterial Infections
- Electrolyte Imbalances
- Fungal Infections
- Legg-Calvé-Perthes Disease
- Nerve Damage From Any Source
- Rupture of Ligaments or Tendons
- Slipped Capital Femoral Epiphysis
- Tears in Cartilage
- Ulcerations of the Skin
- Viral Infections
Causes of Leg Pain
Ankle Pain (Tendinitis)
Ankle pain is commonly due to a sprain or tendinitis. The severity of ankle sprains ranges from mild (which can resolve within 24 hours) to severe (which can require surgical repair). Tendinitis of the ankle can be caused by trauma or inflammation.
Arthritis (Joint Inflammation)
Arthritis is inflammation of one or more joints. When joints are inflamed they can develop stiffness, warmth, swelling, redness and pain. There are over 100 types of arthritis, including osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, lupus, gout, and pseudogout.
A broken bone is a fracture. There are different types of fractures, such as: compressed, open, stress, greenstick, spiral, vertebral compression, compound, and comminuted. Symptoms of a broken bone include pain at the site of injury, swelling, and bruising around the area of injury. Treatment of a fracture depends on the type and location of the injury.
Burns (First Aid)
Burn types are based on their severity: first-degree burns, second-degree burns, and third-degree burns. First-degree burns are similar to a painful sunburn. The damage is more severe with second-degree burns, leading to blistering and more intense pain. The skin turns white and loses sensation with third-degree burns. Burn treatment depends upon the burn location, total burn area, and intensity of the burn.
A bursa is a fluid-filled sac found in the joints that cushions them. Bursitis is an inflammation of the bursae, most commonly caused by repetitive motion. Bursitis can be caused by a bacterial infection and should be treated with antibiotics. Doctors also recommend icing and resting the joint.
Cellulitis is an acute spreading bacterial infection below the surface of the skin characterized by redness, warmth, inflammation, and pain. The most common cause of cellulitis is the bacteria staph (Staphylococcus aureus).
Charcot-Marie-Tooth Disease (CMT)
Charcot-Marie-Tooth disease is one of the most common inherited neurological disorders. Charcot-Marie-Tooth disease affects the peripheral nerves. CMT symptoms and signs include weakness of the lower leg muscles and foot, foot drop, foot deformities, etc. There are several forms of Charcot-Marie-Tooth disease. Inherited gene mutations are the cause of Charcot-Marie-Tooth disease. There is no cure for Charcot-Marie-Tooth disease, however, therapeutic measures and mild exercise may help symptoms.
Chondromalacia Patella (Patellofemoral Syndrome)
Chondromalacia patella (housemaid's knee or secretary's knee) results from misalignment of the kneecap as it slides over the lower end of the thigh bone. Symptoms include tightness or fullness in the knee area, swelling, and mild discomfort. Treatment includes the use of anti-inflammatory medications, in addition to stretching, strengthening and icing the knee.
Cold Agglutinin Disease
Cold agglutinin hemolytic anemia or cold agglutinin hemolytic disease, is rare disorder of the autoimmune system. There are two types of cold agglutinin disease, primary and secondary. Characteristics, symptoms, and signs of in cold agglutinin disease are premature destruction of red blood cells in the body’s natural defense antibodies. The lifespan of red blood cells is approximately 120 before the spleen destroys the antibodies. In cold agglutinin disease, the severity of the condition is determined by how long it takes for the red blood cells to survive, and at the rate that the bone marrow continues to produce more red cells. Immune hemolytic anemias are classified by the optimal temperature when the antibodies try to destroy red blood cells. Cold agglutinin anemia occurs at temperatures between 10 C (50 F) and 37 C (F 98.6) or above while the body warms antibody hemolytic anemia. Usually, cold agglutinin anemia becomes apparent between the ages of 50 to 60. Other symptoms of the disease include fatigue, jaundice (yellowing of the skin and eyes), fingers and/or toes are cold and sweat, an uneven bluish or reddish discoloration of the toes, ankles, and wrists (Raynaud's syndrome), and fingers. Usually, cold agglutinin anemia affects people that are older. The disease is diagnosed by a physical exam, and the Coomb's test. If the red blood cells destruction seem to be slowing on its own, treatment therapies, usually, isn’t needed. Other treatments for cold agglutinin anemia are corticosteroids, and splenectomy (removal of the spleen). There is no cure for cold agglutinin disease.
Cuts, Scrapes, and Puncture Wounds
Cuts, scrapes, and puncture wounds are common, and most people will experience one of these in their lifetime. Evaluating the injury, and thoroughly cleaning the injury is important. Some injuries should be evaluated by a doctor, and a tetanus shot may be necessary. Treatment will depend upon the severity of the injury.
Deep Vein Thrombosis (DVT, Blood Clot in the Legs)
Deep vein thrombosis (DVT) is a blood clot in the deep veins, and can be caused by broken bones, trauma to a limb, immobility, medications, smoking, cancer, genetic predisposition, and cancer. Symptoms of a deep vein thrombosis in a leg are swelling, tenderness, redness, warmth, and pain. Treatments for DVT include medications and surgery.
Diabetes (Type 1 and Type 2)
Diabetes is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Treatment of diabetes depends on the type.
Diabetic Neuropathy (Symptoms, Causes, Diagnosis, Treatment)
Diabetic neuropathy a condition in which nerve damage has occurred as a complication of diabetes. The pain from the nerve damage can be severe with tingling or numbness in the part of the body affected. Diabetic neuropathy can occur anywhere in the body. Diabetic neuropathy can cause symptoms like intense pain, numbness, burning, or tingling in the part of the body affected by the condition. There are four types of neuropathy include peripheral, autonomic, proximal and focal. Natural therapies and medications may help relieve the pain and other symptoms of diabetic neuropathy.
Fatigue can be described in various ways. Sometimes fatigue is described as feeling a lack of energy and motivation (both mental and physical). The causes of fatigue are generally related to a variety of conditions or diseases, for example, anemia, mono, medications, sleep problems, cancer, anxiety, heart disease, and drug abuse.Treatment of fatigue is generally directed toward the condition or disease that is causing the fatigue.
Buildup of uric acid crystals in a joint causes gouty arthritis. Symptoms and signs include joint pain, swelling, heat, and redness, typically of a single joint. Gout may be treated with diet and lifestyle changes, as well as medication.
Guillain-Barré Syndrome is an autoimmune disease of the nervous system due to damage to the myelin sheath around nerves. It is the most acquired nerve disease (neuropathy) and usually follows a virus infection but can also be associated with immunizations, surgery, and childbirth. The cause is unknown but appears to be related to autoimmune reaction. Symptoms include weakness beginning in the legs and progressing upward, lost reflexes, and in severe cases breathing can be affected. Patients can expect a slow but progressive recovery over several months maintaining vital functions and passively exercising the muscles. Plasmapheresis (removing toxic substances from the blood) has been shown to improve outcome and shorten the disease as well as intravenous immunoglobulin.
Hamstring injuries may range from minor strains to major ruptures. A hamstring injury causes spasm, tightness, and tenderness. More severe injuries may cause swelling and bruising. While most hamstring injuries heal without surgery, a complete rupture would require surgery.
A herniated disc may be caused by injury or degeneration from age. Symptoms depend on the location of the herniation and whether nerve tissue is being irritated. An MRI or CT scan is performed to diagnose a herniated disc. Treatment may involve physical therapy, cortisone injection, pain medications, anti-inflammatory medications, muscle relaxants, and surgery.
Iliotibial (IT) Band Syndrome
Iliotibial band syndrome is an overuse injury of the thigh and knee. Symptoms include knee pain and possible swelling. Treatment may involve anti-inflammatory medications, physical therapy, ultrasound, massage, using a foam roller at the site of pain, and the use of orthotics.
Lumbar Spinal Stenosis
Lumbar stenosis can be caused by degenerative arthritis (the most common cause), tumor, infection, or metabolic disorders (Paget's disease of the bone). Symptoms include low back pain, weakness, pain, numbness, and loss of sensation in the legs. Other conditions may cause similar symptoms of lumbar stenosis, including diabetic neuropathy, claudication, and peripheral vascular disease. Lumbar stenosis may be treated with medication or surgery.
Lupus (Systemic Lupus Erythematosus or SLE)
Systemic lupus erythematosus is a condition characterized by chronic inflammation of body tissues caused by autoimmune disease. Lupus can cause disease of the skin, heart, lungs, kidneys, joints, and nervous system. When only the skin is involved, the condition is called discoid lupus. When internal organs are involved, the condition is called systemic lupus erythematosus (SLE).
Muscle cramps are involuntarily and forcibly contracted muscles that do not relax. Extremely common, any muscles that have voluntary control, including some organs, are subject to cramp. Since there is such variety in the types of muscle cramps that can occur, many causes and preventative medications are known. Stretching is the most common way to stop or prevent most muscle cramps.
Muscle spasms are involuntary muscle contractions that come on suddenly and are usually quite painful. Dehydration, doing strenuous exercise in a hot environment, prolonged muscle use, and certain diseases of the nervous system may cause muscle spasms. Symptoms and signs of a muscle spasm include an acute onset of pain and a possible bulge seen or felt beneath the skin where the muscle is located. Gently stretching the muscle usually resolves a muscle spasm.
Neuropathic pain is a chronic condition that leads to ongoing pain symptoms. Patients can be predisposed to developing neuropathic pain who have conditions such as diabetes, cancer, stroke, HIV, vitamin deficiencies, shingles, and multiple sclerosis. Patient history and nerve testing are used to diagnose neuropathic pain. Antidepressants, antiseizure medications, and other types of medications are used to treat neuropathic pain. Many people with neuropathic pain are able to attain some level of relief.
Osgood-Schlatter disease, a painful inflammation just below the knee but above the shin, typically affects adolescent boys. Symptoms include localized pain, inflammation, swelling, and calcification. Osgood-Schlatter disease typically goes away over time, however, symptoms can be helped with anti-inflammatory and pain-relieving medications, ice, and rest.
Osteoarthritis is a type of arthritis caused by inflammation, breakdown, and eventual loss of cartilage in the joints. Also known as degenerative arthritis, osteoarthritis can be caused by aging, heredity, and injury from trauma or disease.
Osteomyelitis is an infection of the bone. Potential causes include injections around the bone, fractures that puncture the skin, recent surgeries, and bacterial infections that travel from other areas of the body, spreading through the blood to the bone. Symptoms include pain, fever, chills, stiffness, and nausea. Treatment involves antibiotics and pain medications. Surgery is sometimes necessary.
Peripheral Vascular Disease
Peripheral vascular disease (PVD) refers to diseases of the blood vessels (arteries and veins) located outside the heart and brain. While there are many causes of peripheral vascular disease, doctors commonly use the term peripheral vascular disease to refer to peripheral artery disease (peripheral arterial disease, PAD), a condition that develops when the arteries that supply blood to the internal organs, arms, and legs become completely or partially blocked as a result of atherosclerosis. Peripheral artery disease symptoms include intermittent leg pain while walking, leg pain at rest, numbness in the legs or feet, and poor wound healing in the legs or feet. Treatment for peripheral artery disease include lifestyle measures, medication, angioplasty, and surgery.
Piriformis syndrome may develop if the piriformis muscle spasms and compresses the sciatic nerve. This causes buttock pain that radiates down the back of the leg along the sciatic nerve. Symptoms include numbness, a pins-and-needles tingling sensation, and low back pain. Treatment of piriformis syndrome depends upon the syndrome's phase: acute, recovery, or maintenance.
Pseudogout, a form of arthritis, results when deposits of crystals collect in and around the joints. Symptoms of pseudogout include pain, stiffness, warmth, and joint swelling of the knees, ankles, hips, shoulders, and/or wrists. Treatment for pseudogout aims to decrease inflammation through the use of nonsteroidal anti-inflammatory drugs, ice, and rest.
Psoriasis is a long-term skin condition that may cause large plaques of red, raised skin, flakes of dry skin, and skin scales. There are several types of psoriasis, including psoriasis vulgaris, guttate psoriasis, inverse psoriasis, and pustular psoriasis. Symptoms vary depending on the type of psoriasis the patient has. Treatment of psoriasis may include creams, lotions, oral medications, injections and infusions of biologics, and light therapy. There is no cure for psoriasis.
There are many types of quadriceps injuries, including strains, contusions, Osgood-Schlatter disease, patellar tendinitis, quadriceps tendinitis, jumper's knee, tendinitis, compartment syndrome, rupture, and herniation. Symptoms and signs of a quadriceps injury including pain, swelling, limping, and decreased range of motion. Treatment of most quad injuries includes rest, ice, compression, and elevation. Ibuprofen may help with pain relief.
Restless Leg Syndrome
Restless leg syndrome (RLS) is a common cause for painful legs that typically eases with motion, and becomes worse and more noticeable at rest. This characteristic nighttime worsening can frequently lead to insomnia. Treatment of the symptoms of restless leg syndrome is generally with medication as well as treating any underlying condition causing restless leg syndrome.
Rheumatoid Arthritis (RA)
Rheumatoid arthritis (RA) is an autoimmune disease that causes chronic inflammation of the joints, the tissue around the joints, as well as other organs in the body. Because it can affect multiple other organs of the body, rheumatoid arthritis is referred to as a systemic illness and is sometimes called rheumatoid disease. The 16 characteristic early RA signs and symptoms include the following. Anemia Both sides of the body affected (symmetric) Depression Fatigue Fever Joint deformity Joint pain Joint redness Joint stiffness Joint swelling Joint tenderness Joint warmth Limping Loss of joint function Loss of joint range of motion Many joints affected (polyarthritis)
Sciatica pain, caused by irritation of the sciatic nerve, typically radiates from the low back to behind the thigh to below the knee. Disc herniation is usually the cause of sciatica. Medication to alleviate pain, physical therapy, and bed rest are treatments for sciatica.
Shin splints result from inflammation from injury to the tendon and adjacent tissues in the front of the outer leg. Shin splints commonly occur in runners or aggressive walkers, causing pain and discomfort. An increase in workout intensity, weak ankles and pronation may be to blame for shin splints. Stretching, strengthening, and icing the affected area are effective treatments for shin splints. Rest and anti-inflammatory medications are also advised.
Sprains and Strains
An injury to a ligament is called a sprain, and an injury to muscle or tendon is called a strain. Sprains and strains may be caused by repetitive movements or a single stressful incident. Symptoms and signs include pain and swelling. Though treatment depends upon the extent and location of the injury, rest, ice, compression, and elevation are key elements of treatment.
A varicose vein is a dilated (widened) tortuous (twisting) vein, usually involving a superficial vein in the leg, often associated with incompetency of the valves in the vein. These visible and bulging veins are often associated with symptoms such as tired, heavy, or aching limbs. Spider veins are a group of widened veins that can be seen through the surface of the skin.
