Anyone have a problem with extremely low Vitamin D and extremely low vitamin B12? I've been having gasto problems too. The Vitamin D was discovered after a lab was ordered by my Psychiatrist. The B12 was discovered by a civilian doctor. Was tired of the army docs telling me that they couldn't figure out my symptoms and I paid out of pocket for a civilian doctor. I'll follow up with the civilian doc when I get paid on the 15th, but I was wondering if anyone had had similar problems and what the diagnosis turned out to be?
