What Causes Bell's Palsy?
Reviewed: Dr. Gromatzky
10. Herpes
The herpes simplex virus is a fairly common virus that is often associated with sexually transmitted diseases. While it is true that it is responsible for genital herpes, it is also responsible for cold sores. These are lumps and/or blisters on your face that can be very painful. They are sometimes triggered by a change in weather or another illness.
Patients won’t usually develop other symptoms in addition to the cold sores, although it can sometimes also cause Bell’s palsy. The virus is very contagious, and people should avoid all contact with the sores where possible. The sores should heal themselves within 10 days or so.
