<<Disclaimer: Verify this information before applying it to your situation.>> I will try to keep this brief. I have a brother in Dallas area who has had problems losing his balance. He had been testing for CD ( don't know which ones) which came back negative. They, however found him b-12 deficient and he has been taking shots. The problem he also had with tingling in his toes has improved but loss of balance has gotten worse. I guess my question is, can anyone share similar symptoms with me ( I do not have these symptoms ) and also can anyone recommend a good gastro MD and a good neuro MD in the Dallas area. Thank you so much.
