I have a boil under my breast (where band of bra sits). I went to the doctor last week (7 days ago) & was prescribed a 14 day antibiotic. She said the boil would drain by itself & my body would absorb puss. The boil is still very painful & now along the side of my breast, moving away from the boil, it is becoming pink and tender. Like the infection/ puss is moving?? (about a 4 to 5 inch area of breast) Just wondering if this is normal or if I should go back to the doctor. (I am also doing hot packs a few times a day & I had to get a topical pain reliever). Thank you.
