I have a very good neuro whose sound advice was: physical and mental rest until you feel 90% with no symptoms. Then begin a graduated return to work.

You might review the six-step protocol for athletes, which mandates rest until symptoms are gone, then increasing activity incrementally, starting slowly and carefully, and stepping back if symptoms are triggered (many people find they initially need to rest completely, sometimes for weeks or even months. However, light activity/exercise during recovery may be helpful so long as it doesn't trigger or worsen symptoms). Recovery can take days, weeks or months - no way to predict a timeline. Be patient and optimistic.

It is very important to make your recovery (not work, not studying, not socializing or exercising) your top priority.
