hey everyone, i have been on interferon for 18 weeks now and 2 weeks ago i got what i thought was just a pimple on my back, but then it grew it a large boil of somekind, after going to my regular doctor he said it looks like you got bit by something maybe a spider and gave me some antibiotics, after a week it went away. now i have what started like a small rash under my right arm but about 5, what look like boils have grown larger and are also painful. has anyone experienced this and is there anything i can do to relieve them without antibiotics. thank you joemc34606
