it sounds like you have folliculitis, which is an inflamed hair follicle. These hair follicles can become so inflamed they turn into abscesses. The abscess can be deep, infectious and very painful, and would have to be surgically removed. If left alone it's possible you could end up with sepsis but that would be in a rare case. Yes you need to be in hospital and get this condition seen to. I've had folliculitis but only in a minor fashion. Mine have never turned into abscesses.
