I was diagnosed with Ulcerative Colitis (UC) in 1980 after many weeks of diarrhea and then bloody diarrhea. It was confined to the last part of my colon. 20 years later I start having problems with my small interstine and after much testing, it was decided that I had Crohn's. Because of undiagnosed Polymialgia Rheumatica, I asked for Low Dose Naltrexone. Low and behold, it healed my small intestine- which had been full of small, blister like ulcers for years. Over 80% of Crohn's patients get benifit from LDN. I certainly did. My last colonoscopy was normal. I reccoment anyone suffering from Crohn's try it. It might help.
