Ive got a red spot under my right breast. It doesnt have any puss in it, and it is slightly raised, i can feel a bump to it when i run my finger over it. It doesnt look like a normal spot as it is over a bigger area. When i was examining it, i noticed quite a few white pimples underneath there too. However i also have a few of these underneath my left breast also, but no red spots. I am 21 and big breasted. Any advice would be much appreciated as i would like to know if there is anything to worry about before i go to my GP as he is male and i dont know him well
