A tick bit me 5 weeks ago. it was engorged, i removed it. 6 six days later a bullseye rash developed. i saw a doctor and took doxycycline for 21 days. i still have a red bump where the tick was removed, should i see a doctor again?

Tick Bite: Definitely see your doctor for follow-up. CDC recommends two-step testing. First step: EIA (enzyme immunoassay). If the EIA is negative, no further testing of the specimen. If the EIA is positive or possible, then a “Western blot” test is ordered. If ill 30 days, only the IgG blot is done. A positive diagnosis requires positive for both EIA and blot
