I notify my neuro if i have new or worsening symtoms for >than 24 hours but if they are not affecting my day to day abilitu to function i just diary them and tell him at next appointment but if i am having problems functioning i notify him at the time so we can consider steroids to try and reduce the symtoms again. Having said that even if the symtoms were not causing too much of a problem, if it was happening frequently i would still give him a ring.
