I'm unable to use the muscles in my right side face properly? Doc says it's viral. Contagious to my family?

No. Multiple websites agree that the virus causing bell's palsy is not contagious. The nih website adds that steroids such as prednisone—used to reduce inflammation and swelling—are effective treatment. Other drugs such as acyclovir—used to fight viral herpes infections —may also have some benefit in shortening the course of the disease.
