i'm sorry you're going through this. it sounds very uncomfortable! what you're going through may not be a bruise. it could be something like a boil. a bruise would not flare up and then come back. a bruise would heal and go away for good. i would recommend you have a doctor take a look at this. while it may be something annoying like a boil it could also be something a bit more serious like a cyst or an infection. of course the sooner your treat an infection the better. i wish you all the best with this!
