I was dxd a while back and the first neuro said "you are too old for MS!" I said "really?! what if I have had it for decades and no one knew it?" and his response was that I would have been dxd before now. He dismissed me. I went to the MS clinic and they said "WOW, you really do have MS." I said the first guy said I was too old! and they said "not if you have had it for years, and no one knew it." Crazy doctors!
