Hey everyone, not long ago i developed a rash in my left armpit which i scratched at pretty furiously. After a while i'd scratched so much that it became sore and then a small lump developed under the skin. It doesn't hurt when i press the lump and it wouldn't be more than 1cm in diameter but it's cause enough to worry me. I've been looking up pages on the web which all suggest it could be a swollen lymphnode that may have caught some malignant cancer cells. If anyone has had a similar problem please let me know, thanks
