<s>[INST] Hello. I have a guilty type lump in my armpit, im 21 years old and haven t yet consulted any doctor for it. Sometime this guilty irritates and is little painful (just as much as it feels something is there). Also i get my armpits waxed and was wondering if this could be something regarding internal pimple growth. [/INST] Hi, dairy have gone through your question. I can understand your concern.
