KASPARA - Welcome to the boards! I hope that you fully utilize this board (and the internet for that matter) as you have limited access to specialists.
I don't mean to scare you, but based on what you're describing it sounds like you have an autoimmune issue, in particular, celiac. Celiac is basically an allergy to gluten (found in wheat, rye, barely and used as a filler in a lot of processed foods and meats). Though there is no "cure," it is EASILY treatable. Once a gluten-free diet is followed the symptoms disappear and the body begins to repair itself. Unfortunately it is a disease that the medical profession often overlooks and tend to narrow-mindedly catergorize patients as needing to be "thin" or have gastrointestional problems. The truth is very little people show those symptoms. The fact that you are having problems moving (inflammation), have a B-12 deficiency, rashes, bloating and menstrual irregularities seem to warrant such a test for celiac. If you are unable to talk to your doctor about testing for it, you can always try a gluten-free diet and see if your symptoms improve.
There is also an area on this board for Canadian cysters so you may want to drop by and see if anyone there can recommend a doctor.
