Have been suffering from folliculitis on the scalp for almost 4 years now. It started as mild bumps on the scalp. I have been to many different dermatologists. All prescribed different antibiotics. Have been on betadine ad shampoo. As long as I am on antibiotics, my scalp will be clear. Once antibiotics are stopped, the blisters and pus returns within 20 days. Since last two months, a dermatologist suggested taking multi vitamin injections every week to boost immune system since I have been on antibiotics for a very long time. The treatment worked and my scalp was clear for about two months. Again since few days the blisters have flared up and has become very painful. Pus culture was done once and it came back negative for any bacterial growth. I have no idea how to proceed from now or what treatments to pursue. Doctors are at a point saying all avenues have been tried. Any help or advice on further course of action will be much appreciated. I am open to further tests as well.
