Big, red, bump leaking pus under arm
koreaprof posted:
About five or six days ago, I had a big, red, kind of tender/painful bump appear in the middle of my armpit. At first I passed it off as a pimple and even tried to squeeze it to reduce some of the pressure but it wouldn't burst. Eventually it started to look a bit white on the top and was able to pop it with only a little bit of white stuff coming out. The pain didn't really stop and it began to get more tender and whitish colored on top.

Now, it seems to be raised even higher and there are two spots where it seems like this yellow pus is coming out at all times. It seems to leak out a little. Right now it is VERY painful.

*I am not sure if it is "spreading" exactly, but I am beginning to feel another small, painful pump about 2 inches above it. So far it has no symptoms other than being raised, red, and painful.

I really appreciate any advice on this matter.

Dear koreaprof,

This does sound like it might be a cyst. Keeping the area as clean and dry as possible might be helpful, though using warm compresses could help the swelling and/or bring the cyst to a head. I do not recommend squeezing this as you can put pressure on the infected material and force it deeper into your body rather than getting it out.

If this continues to spread or develops a greater degree of infection, you may wish to be evaluated. Some people develop a condition where they develop numerous cysts in their underarm area.

I went to the doctor today because it kept getting worse and more painful.

The problem is that I am in Korea and I don't exactly trust the doctors here.

The doctor squeezed the heck out of it and basically left a crater there. I hope it will get better and not return.
Susan Evans, MD replied to koreaprof's response:
Keep this area clean and dry now. Certainly wash it when you bathe, but then keep it covered until it begins to heal. Most of the time this will heal without any additional intervention on your part. Keep us posted.
