<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have had a recurring rash where my arm and bicep meet for a couple years. It comes and goes over time but has been re-appearing lately. I have tried Cortisol cream and it seems to lessen the redness but do not know what it is. It does not itch, but just appears in red blots with 4-5 inches lengthwidth. I am pretty active with lifting weights and running as well, but do not use that sections for lifting. Also, it is only on my right arm. Any help would be fantastic. Thanks!  <response>: Hello, The symptoms as mentioned in your post suggest that you might be having fungal infection.
