I have had a skin rash small bumps that itch slightly a few weeks ago on the backs of both thighs, now three weeks later on the back of one thigh and around the back of the right side of my waist. I dont have pets and use the same laundry soap - hypo allergenic ecos- that I have used for awhile now. What could be wrong?
Hi and thanks for the query, the fact the rash is evolving despite the Chat Doctor.  It is possible it could still be an allergy, but reevaluation of the rashes could be important to re-adapt or change the treatment. It is however not excluded that it could also not be an allergy, considering it is spreading it is spreading at a fairly not very rapid rate, and that no actual predisposing allergen is incriminated. Consulting your primary care physician would be necessary in characterizing the rashes and making a distinction between rashes of infectious or allergic origin. This would aid in doing further appropriate testing and exact diagnosis. I suggest you consult you primary care physician for a complete clinical evaluation and management. Thanks and best regards, Luchuo, MD.
