Hi there, I have itchy flea bite like lumps all over my scalp and neck. I mean they are really itchy. I went to the doctor and he prescribed antibiotics. I took the whole course, but nothing, no change, in fact it spread from just being on my scalp, down the back of my neck. I have been in the ocean with the thought that the salt water might assist, but no. I now have my head doused in tee-tree oil to see if this helps. What are your thoughts?
