[|Human|] Hello: I have developed very large circular, flat discolorations on my back that at first, looked like bruises ie: sort of dark red. I have two that are perfectly round and two that are very large and oblong. I went to my primary care and he stated he thought it was exzema and gave me a topical cream, however, they do not itch , not raised, not dry or flaky. Only knew they were there because someone pointed it out to me. Within the last two days, I have developed two more, one on my hip and one on my shoulder blade. Could this simply be an allergy? I do take Simvistatin (40mg) and have been for approximately 1 year. I am 53 years old and have never experienced anything like this. I live in Florida (humid climate) and have been under stress so not sure if these things contribute. Any guidance would be appreciated.
[|AI|]  Hello and welcome to ChatDoctorcould you please clarify how large the lesions are and where precisely they are located i.e. upper back or lower. You mentioned living in a humid climate, do you sweat a lot? Do you have oily skin? Does anyone else in your immediate surroundings have these lesions. I would advise you to have a basic blood test done and visit a dermatologist this condition you are having might be a simple fungal infection(Tina tricolor). Allergies to Chat Doctor. Good luck
