I am having a painful armpit boil for last two months. Its soft to touch but when I stretch my hand to max it feels hard to touch. It has a mouth like a pimple and it's painful. I shaved one day and was wearing tight clothes and it started.i sweat a lot and it increasing with sweating.i had mild antibiotic medicine for 3 days to get this resolved but it didn't go away. By mistake I reshaved over it and since then it has again grown and painful. I don't get time to apply warm compress. Its like a small ball size of a medium round pill. Initially it was extremely painful but now that has reduced and even the size but it's not going away completely. What should I do??? Please help. It started right after shaving and in extreme heat one day.i exercise also and it might be getting worse with sweating. What should I do?
