When to seek medical advice
By Mayo Clinic staff
If you've been bitten by a tick and experience symptoms
Only a minority of deer tick bites lead to Lyme disease. The longer the tick remains attached to your skin, the greater your risk of getting the disease. If you know you've been bitten and experience signs and symptoms of Lyme disease — particularly if you live in an area where Lyme disease is prevalent — contact your doctor immediately. Treatment for Lyme disease is most effective if begun early.
See your doctor even if symptoms disappear
It's important to consult your doctor even if signs and symptoms disappear because the absence of symptoms doesn't mean the disease is gone. Left untreated, Lyme disease can spread to other parts of your body from several months to years after infection — causing arthritis and nervous system problems. Ticks can also transmit other illnesses, such as babesiosis, Colorado tick fever, anaplasmosis and ehrlichiosis.
