Hi,
Thank you for posting your query.
Yes, I agree with you partly that cold could trigger the viral infection causing Bell's palsy.
It is common for patients with Bell's palsy to develop it after being exposed to cold air or direct AC wind.
The causative viral agent for Bell's palsy is believed to be
herpes simplex virus (and not HPV). HPV can cause cancer of
cervix.
As of now, the treatment would be anti-viral drugs such as
acyclovir and oral
steroid tablets.
In addition,
physiotherapy and facial exercise would also help.
I hope it helps. Please get back if you require any additional information.
Wishing you good health,
