Wow your story is so familiar and encouraging!
I have had a very similar course, with similar findings but for some reason I cant seem to let it all go. I'm going on to see a Neuro-Muscular specialist to look into my hand atrophy closer. But hearing something similar with a positive outcome is encouraging! I want so much to take your advice and listen to the Neuro when he tells me that he has ruled out ALS. It jsut seems still odd to me I guess...
