The people here are not doctors. All they can-and have--told you is true: You don't sound like a victim of ALS. Trfogey types with his HEAD mouse. Toto is in just as bad shape--and they've tried--only to be called inconsiderate. Insist on a swallow study--see if your back is fixable--and they can EMG a tongue--but it hurts like hell
if your doctors were seeing the atrophy you are seeing--they'd have you going weekly til they found answers. Apparently, they aren't finding it. it takes time for Vit. D to get back up to level--and for Low T. Wait and see how you feel after those two are addressed.
