YOU HAVE WHAT IS CALLED ECZEMA I HAVE THE SAME RASH AND IT DONT GO AWAY UMMM BUT WHAT U CAN DO TO KEEP IT CLEAR I MEAN IT WANT GO AWAY BUT USE UNCENTED LOTIONS AND SOAPS AND USE VASALINE TO KEEP IT MOSTRIZED THOUGH OUT THE DAY.
Get tested for Lyme right away. If you have it, time is of the essence! It spreads fast. I had it for 10 months without a diagnosis and I've been treated now for 3 months with 43 symptoms! Trust me, you do not want Lyme!
Are you on any meds? Could be erythema multiforme, which is a circular red rash with a white center, often causes by an allergic reaction or infection.
however, Some classic circular rashes are ringworm and Lyme, so it would be a good idea to have a doctor look at it.
