Hello all, I've just registered with the forum, though I have been reading it for a few months now. I was diagnosed in July 2011, aged 55. I'd had so many seemingly unexplained symptoms for so many years but was never examined for crohns despite having two cousins with it, a fact I had always told GP's about. Finally, collapsed with perforation last year and spent 10 days in hospital although it still took them 9 days to diagnose the problem! I had I/C resection in Dec 2011 and had been feeling really well until about 2 weeks ago. I am now having pain in many joints and severe tingling,mainly in spinal nerves but also sporadically all over. Doc doesn't seem to think this is connected with crohns but having read some of your posts I'm thinking maybe it is. I have low B12 and regularly have potassium slumps! I am so angry that my GP doesn't seem to think crohns is very serious and that now I have had my expensive! surgery I should be OK from now on. I am still trying to accept the fact that I even have this dreaded diagnosis, before I was diagnosed I seemed to be able to just carry on but now the smallest thing really gets me down. It really helps to know I am not on my own and find your posts really helpful.
