Like Kel, I've had most of those MS symptoms, although, many of them, only once...As in..loss of hearing, ON, dbl vision, vertigo, shingles, that falling side of face and eye thingy (help me with the name of it).
I've had the tingly, numbness, dizzness, weakness and spasticity from the beginning and have slowly lost the ability to walk

, but can still stand and tranfer

(mostly).
I was DXed in 1976 and again in 1993. so yes, to your second question..., a lot of those symptoms didn't happen until the 1993 period and after.
