Hi, so I have this big, painful bump on the back of my neck. Its been here for a few days but it started out as just a tender red spot, it seems to have been getting bigger and more painful everyday and now Id say its a little bigger than a quarter and is a purplish-black.  Its painful to the touch, and even when I dont touch it. Turning my head, looking down or up, putting on a shirt, washing my hair all hurt it to the point where im practically in tears.  It has a head, but before it got as bad as it is now I tried squeezing it, nothing but blood came out. I cleaned it a bit last night (just with peroxide and then some neosporian and put a bandage on it) and it was pussing a very very little amount, barely noticable.
Hi, This may be an infected sebaceous cyst. From your description of the pain, I would suggest you need antibiotics. Either see your doctor or go to the ED. Take paracetamol and Ibuprofen for the pain. Apply clean Chat Doctor.
