question: I had a lump under my arm which was a little sore, i went to the doctore whom gave me some antibiotics, I then developed thrush, so had to buy canestan combi, which isnt cheap, I now have another lump under my other arm, similar to the last one. I am currently exercising very hard and wondered if this could have something to do with it. Can I just leave it? I am reluctant to go back to the doctor, even with the antibiotics it didnt go away until after the course was completed. It is not a hygeine issue as i shower twice a day. Could you offer any advice
