i am betting on a low B12....if the newer doc (with newer education) wanted to supplement i would bet it is below 500......i would also bet that your condition is going to be multifactorial....an MRI of L/S spine an evaluation of your work station.....do you need glasses? or new ones, ie are you altering your posture antagonizine your L/S area? are your feet planted firmly on the floor, avoinding pressure on the back of your thighs (part of Glenn"s double crush idea). fasting glucose really isnt worth the powder to blow it to you know where.....especially with family hx, and you are getting into the right age group. and my favorite, gluten intolerance/celiac disease. See, you were correct in posting here! Isnt it lovely when we are blown off by our own,not!
