Tick bites are usually harmless and may produce no symptoms. However, some people may have an allergic reaction to a tick bite. This reaction may be mild, with a few annoying symptoms. In rare cases, a severe allergic reaction (anaphylaxis) may occur.
Anaphylaxis symptoms may include:
- Sudden raised, red areas (hives) all over your body
- Swelling of the throat, mouth, lips, or tongue
- Trouble breathing
- Passing out (losing consciousness) or you may feel very lightheaded or suddenly feel weak, confused, or restless
Bring the person immediately to the emergency room of a hospital if he or she develops these symptoms.
Tick bites may also get infected. See your doctor if you develop the following symptoms:
- Increased pain, swelling, warmth, or redness around the bite
- Red streaks leading from the bite
- Pus draining from the bite
Watch closely for changes in your health, and be sure to contact your doctor if:
- You develop a new rash.
- You have joint pain.
- You are very tired.
- You have flu-like symptoms.
- You have symptoms for more than 1 week.
