Thank you for waiting.
I understand your concern.
I am very sorry for your symptoms.
The symptoms sound like facial nerve palsy.
The common cause is Bell's palsy.
But it needs to be confirmed by doctor.
It usually improves in weeks.
It is thought that the disease is caused by infection of nerve by virus & it gets pinched in a narrow bony canal of the skull through which it passes.
Treatment options are physical therapy, steroids & antiviral therapy.
Please do not worry.
I hope this information will be helpful.
If you have any query, please feel free to ask.
Your satisfaction is my goal.
