 [ Symptoms ] i was told yesterday that my baby has no heart rate at 38 weeks and 3 days [ Disease ] i am sorry you are going through this it sounds very uncomfortable what you are 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
