Does he have Epilepsy also?
Just wondered as this is posted in the Epilepsy forum.

[he also experienced weakness in the right hand and right leg but quickly recovered.]

Our General Health Conditions & Rare Disorders might be a better fit.

Also use the search link in my siggy to find other posts for Bells Palsy, that might be the best way to find other posters on the condition.
