<s>[INST] A bump under my skin on my lower stomach/pelvic area appeared suddenly.  I thought that it was an ingrown hair but it was very painful and tender to the touch.  Another one appeared the next day a little lower. The first one has stopped hurting, decreased in size, and turned a purplish color as opposed to the red that it was.  Now there is one in my armpit and it is very painful.  I don't know if it's swollen lymph nodes, ingrown hairs, cysts, boils, or something else. I'm starting to get really concerned.
