I've noticed this little spot come up on my breast, about an inch above my areola, over the last couple of days. Today it's hard and slightly hot to touch and I can feel a swelling around the general area. It's painful when prodded but otherwise I'm not really aware of it. I'm thinking it could be an ingrown hair - but I can't recall having one before so I don't really know what they look like. I can't find a head on it either.
I just wondered if anyone could advise on what it might be. I'll go to the GP if I need to, generally try to avoid it at all costs
but I do realise that no one can really diagnose online.
