It may not be an "official" symptom but I have numbness issues that I believe are related to my acid reflux. I have laryngopharengial reflux (irritation gets all the way up to my throat)  When I have eaten things I shouldn't or havn't been good about medications I have numbness issues in face first and then it can continue to arms and even my leg if I don't correct what I am eating/doing.  I am convinced it is related.  I am not a doctor but after a complete neurological workup and no answers from doctors I am assuming it is related to some type of inflamation that is pushing on a nerve somewhere.  Now that I am reading about others with similiar issues I am even more convinced.
