According to Healthline, tick bites tend to be harmless and seldom produce symptoms other than small red bumps, but some people experience swelling, burning, a rash or blisters at the bite site. Symptoms of tick-borne diseases, which require immediate medical attention, include headaches, muscle and joint pain, nausea and fever.
Symptoms of illnesses such as Lyme disease, Colorado tick fever and relapsing fever become apparent one day to three weeks after a tick bite, according to WebMD. Ticks tend to remain attached to their hosts, and proper removal decreases the likelihood of contracting a tick-borne disease. Use tweezers to remove ticks by grasping them as close to their mouth parts as possible to avoid squeezing their bodies and releasing infected fluid into the skin.
