This is a quote from one of the message forum pages on TM website:
Even though the lesion(s) are gone, there may be underlying nerve damage caused
by the inflammation and the fact that the nerves were "unprotected" once the
myelin got "eaten" away. The myelin grows back at 1mm a day, so it takes a
while for the body to repair itself, BUT the nerve can remain damaged.
You will know what damage is left at the 2 yr mark. After this you can still
have some recovery but it is very small and unlikely to be very noticeable.
