What are the symptoms and signs of a hematoma?
Symptoms of a hematoma generally depend on its size and location. Pain, swelling, redness, and disfiguring bruises are common symptoms of hematoma in general. Some symptoms specific to the location of a hematoma are:
- Subdural hematoma symptoms: headache, neurologic problems (weakness on one side, difficulty speaking, falling), confusion, seizures
- Epidural hematoma symptoms: back pain, weakness, loss of bowel or bladder control
- Subungual hematoma symptoms: nail pain, nail weakness, nail loss, disfiguring nail
- Splenic, hepatic, or peritoneal hematoma symptoms: abdominal pain, flank pain
Sometimes there are not any symptoms at all associated with even a very large hematoma. For example, if bleeding happens to be inside the abdominal cavity, it can expand into a very large size before it causes any symptoms. This can happen because the hematoma can spread in a relatively free space without pressing on any organs to cause pain or other symptoms.
On the other hand, a small hematoma under the nail can present with a lot of pain because the blood expands into a very tight space under the nail bed and causes inflammation and irritation of the nearby nail and skin, resulting in pain and swelling.
Depending on the location of the hematoma, a mass or lump can sometimes be felt.
