<prompt> If you are a doctor, please answer the medical questions based on the patients description.I had a lump under my arm for about 2 months. A doctor was going to do a biopsy and then decided not to. I kept cleaning the area well and it finally went away. Then a sore and painful rash appeared in thes same area. It was there for about a month and again finally went away. Once more, my doctor just told me to keep an eye on it. Now, I have some soreness in the muscles from this same arm. Should I be worried and consult a different doctor?  <response>: Hi. Thanks for your query and an elucidated history. Definitely yes, You should consult another Doctor :: the reason being there is still a problem, and it is possible that the Doctor only can examine properly to find out if there is a lump and associated findings and can go for a few tests if he is suspicious of something. IF he does not find anything you too are reassured, is not it ? Please go ahead.
