Painful lump on head with a rash on my neck
I noticed one day that I had a lump on the back of my neck. I assumed it was a swollen lymph node because it is right where the occipital lymph nodes are. It is very itchy, and there was a small rash on my neck below it. Each day the lump got larger and is spreading, and the rash got worse. I tried taking some antibiotics, but the next day the rash had spread from the back of my neck to my collarbone. Does anyone know what this is or what I need to do for it?
