My husband had something that was similar to Bechets or it could have been pyoderma gangrenosum. His skin blistered and started to ulcerate in spots, it was terrifying. I ran across this article and we started him on potassium iodide 1200 mg per day divided into 4 doses (300mg 4 times a day). Yes, you read that right, mg, not mcg. It immediately started healing his ulcerations which had been rapidly worsening. He took that dose for 2 weeks and then took one additional week to wean off. Highly recommended.
