Several years ago I was broke out in boils and blisters all over. I had several biopsies that indicated infection. I tried a variety of meds and they were about to send me to Emory because the Dr was at his wits end. FINALLY he placed me on a Supha drug and that did the trick. I was clear for several years...got sick last year and started breaking out again. I told my Dr to give me Sulpha and I cleared up w/in 10 days.
