My wife is freaking out right now and she is not getting any answers. I am not sure if this is even a dermatology issues but she has been experiencing some pain in the upper arm by the biceps for nearly a month now. She has noticed recently there was a semicircular marking around a small mole she has that seems to come and go. She went to doctors office about it and they said they don't know what it is. She is now saying that she is experiencing the same type of pain in the other arm now around the same location. I thought it might be something like MRSA but only guessing here. Any Ideas? Thank you
