The guidelines for Tick bites have changed so it would be strongly advisable to contact your physician if you have had a tick bite or if the tick is on you.
If biten by a tick and it is a deer tick AND has been attached for over 24 hours it can be treated with a single dose of doxycycline. This treatment is to prevent Lyme disease and this regimen can be used up to 72 hours after tick removal. Call your physician as soon as possible so appropriate preventive treatment can be given.
If you have a bulls eye rash after a tick bite or multiple circular rashes you should contact your physician for evaluation and treatment.
Other signs of Lyme disease may be joint pains or joint swelling, headache or neck pain, facial palsy or vague chronic symptoms. For any of these symptoms it is important to see your physician for evaluation.
