I Was Just Diagnosed With Lyme Disease By My Dermatologist.

I was just diagnosed with lyme disease by my dermatologist. I was in her office two months ago with a oblong rash on my left breast and she had me purchase some ointment and come back and see her if the rash persisted. I now have three rashes so her conclusion was Lyme disease. I do have some joint pain but Im 57 years old and I run and walk for exercise. My rashes are not bullseye rashes.
