I had hives. After a couple of weeks of itching, it turned into puss dripping scar looking wound. Its been a couple of weeks and I am using bacterium ointment and doxy antibiotic, but it doesn't seem to subside. I developed itchy lesion-turned-dripping wound on my ear as well as forehead. About the same time when it all started, I had very itchy rashes broke out on my hip and lower legs which is now subsiding. About 3 years about I went through similar situation when I my skin had reaction to PPD of hair dye. Not sure what it got reacted to this time, if any. If anyone know how to fix this, I would very much appreciate the help. PS I have been on low histamine diet for the last 2 weeks. Thank you!
