The way I think about things is that when there is a symptom e.g. tingling face, that means the myelin has been destroyed in area xyz and the message has failed finally to find an alternative path around the damage.
Failure to re-route and consistent damage in the area = symptom.

With time and dmd's (?), the area 'repairs' or finally a signal finds its way around the damage and the symptom lessens.

With me so far?

So when we're in remission, symptoms have improved and signals are getting through as best they can.

Question; IF the same symptom comes back after a year, is that indicative of new damage in the area surrounding the 'old' damage?
OR is it new damage elsewhere that appears as the same symptom?
OR is it something else that my little brain cant work out?

IF it's an 'old' symptom that comes back after a year, is it a new relapse? Or an old unhealed scar that's playing up?

What do you reckon people?
