Got FD possibly working in the hospital. Cause remains unknown. Had it for 4 years. Primarily on the back of my scalp, crown, and sides. Have alopecia as well. Tried Antibiotics but it reappears every time the Antibiotics are stopped. Topical clindamycin worked great for over a year until my scalp became resistant. Would highly recommend it if you're not on it. It's not systemic and is safe for topical application. All the other stuff is nonsense. Tried it all. Turmeric, vinegar, bleach, selenium sulfide, desetin, anti fungals, etc. as of now there is no cure. I continue reading every medical study and case report and they're all baffled for now. It sucks but there are more serious life threatening diseases such as Lou Gehrig's disease and countless more. So stay positive until there's a cure
