I've resently had Colonoscopy and the results have come back that I now may have Crohn's disease. I have suffering with really bad mouth ulcers for quite sometime that weren't healing up, lots of other symptoms but no one put 2 and 2 together. I was diagnosed with an under active Thyroid last October so a lot of the symptoms we put down to that. Feeling rather down about it., was wondering if it is linked? I'm ready other peoples blogs and they are in a lot of pain, I'm not really, have back ach and pains in legs fatigue joint pain and bad mouth users. I am bleeding and the mucus. They said the ulcers were in the lower part near the rectum and there was inflammation top and bottom bowl. But I thought I'd be in more pain, just feel so tired. They've taken full bloods and I'm not lacking in any vitamins. So not sure why I feel like this?
