Symptoms of Tickborne Illness
Many tickborne diseases can have similar signs and symptoms. If you get a tick bite and develop the symptoms below within a few weeks, see your healthcare provider.
The most common symptoms of tick-related illnesses include:
- Fever/chills. All tickborne diseases can cause fever.
- Aches and pains. Tickborne diseases can cause headache, fatigue, and muscle aches. People with Lyme disease may also have joint pain.
- Rash. Lyme disease, Southern tick-associated rash illness (STARI), Rocky Mountain spotted fever (RMSF), ehrlichiosis, and tularemia can cause distinctive rashes.
Your healthcare provider should evaluate the following before deciding on a plan for treatment:
- Your symptoms,
- the geographic region where you were bitten, and
- lab tests, depending on the symptoms and the geographic region where you were bitten.

Tick paralysis is thought to be caused by a toxin in the saliva of an attached tick. People with tick paralysis can experience weakness or paralysis that gradually moves up the body. These symptoms can sometimes resemble other neurologic conditions (for example, Guillain-Barré syndrome or botulism). Patients typically regain movement within 24 hours of removing the tick.
