Hi there Tony. Thank you for posting your question with Healthcaremagic. I will do my best to help you.
This may well be Bell's palsy
. If so you will need to go on steroids
. The other possibility is a small CVA or stroke
. It is a neurological problem and you need to see a doctor. Just ignoring it is not very wise.
I hope that I have answered your questions fully and been of some help. If you have anymore questions please contact me again anytime.
Dr Andrew Rynne.
