What are tick bite symptoms and signs?
Unfortunately, the tick bite is usually painless and remains that way even after the tick stops the blood meal and falls off of the skin. Later, the bite site may develop itching, burning, redness, and rarely, localized intense pain (some soft tick bites) in some individuals. A few individuals may be sensitive or allergic to tick bites (tick saliva secretions) and develop rash, shortness of breath, swelling, numbness, or paralysis. However, the majority of individuals with tick bites develop no symptoms, and many do not remember getting bitten.
Some immediate symptoms that infrequently or rarely develop during or immediately after a tick bite may be fever, shortness of breath, weakness, vomiting, swelling, weakness or paralysis, headache, confusion, or palpitations. Individuals with these symptoms should be seen immediately by a doctor.
