For ever a year now I get these huge quarter to dime size pus and blood filled bumps they are very painful to touch and then drain after a few days still incredibly painful. Recently they have spread to my inner thighs and around my waist they leave a scar and some are recurring in the same location I also have one on my breast. The other day one popped on my leg I was cleaning it up when I noticed it had a hole in it. Today I was cleaning up another one and it also had a hole this one was bigger and I can even see inside it. What is this? I can t find anything about it online I m starting to get scared.
