At one point it was like a bubble and it drained just like a cyst. I do get those here and there from time to time, but this is different doesn't seem to want to heal. Its like it burst open drained and left a hole that will not heal. It's constantly wet and seems to be discharging on a regular basis in small quantities.
It seems that it may be a Staff Infection, which you can get on anywhere on the body, and will go away and sometimes come back if you get another infection! I have two friends that have had this recently. It normally does require medical attention. You will probably need an IV for a few or so days. And get it properly drained and bandaged for it to heal up. Hope that this helps you!
