Ive had a lump on my armpit for about a week now. Its about the circumference of a quarter or bigger and it hurts quite a bit when i move my arm certain ways. It has a little bit of red on the surface like a small part of it as if it was a zit, but i highly doubt its just a zit.
i read lymphoma lumps dont hurt AND my brother was diagnosed with that about 6 months ago and is under going treatment. so i dont think i would have it too. i dont think god would make a family go through that twice and at the same time.

any ideas what it is??
