I recently was having what I thought was a relapse (increase in symptoms). I thought that a flare-up was an increased intensity in symptoms within the relapse period. During all of this I had to have surgery, wrist reconstruction. I came home the same day and the next day I was just short of seizures and was coverd with electrical shocks, (L'Herette's). I had to be taken to the ER. Was sedated to the point of being put to sleep. This lasted about 24 hours. I have been having this same type of problem following previous surgeries or injuries. Been dealing with MS for a long time but these are nightmarish.
