Hi, I am 63 years old and was diagnosed with crohns in 2008. Since then I have rarely felt well. I have been prescribed large doses of prednisolone which worked at first but do not seem to have the same effect now. I tried Pentasa which did not work at all , azathioprine which made me vomit non stop and am now on Mercaptopurine. I seem to go a few weeks and not feel too bad but then suddenly I seem to be back to square one, totally worn out, feel rather dizzy and spaced out and just cannot be bothered with anything in fact I am becoming very depressed with how I feel, this has just taken over my life. Also now, I don't know if anyone else has experienced this, but my tongue is very coated and sometimes it is as though my mouth is burning. Anyway, I would love to hear from others as it is easy to feel very alone with this problem and I seem to get nowhere with doctors and specialists.
