Since June this year my sister has been having a problem with her skin. It starts out looking like a bug bite, but it doesn't itch. Then it turns black and swells like a sausage under her skin and it's extremely hot to the touch. She has had to have surgery to clean all the crap out under her skin. Normally it's filled with puss. She gets them on her thighs and one time on her arm. Antibiotics seems to make it go away. But every week or 2 there is a new one forming. Can anyone please tell me what this is?!View Thread
