It is my understanding that if the Bell's Palsy is caused by a virus, then doctors are supposed to give the proper antiviral drug within the first 48 hours---the sooner the better from onset of symptoms----in order for the drug to do any good. The antiviral drug can really help lessen the symptoms and duration. I hope your friend was offered this type of treatment. My niece was in her early twenties when this happened, and she had the viral treatment drug and recovered completely and fairly quickly. My sister didn't get the med as soon as she should have and her symptoms lasted a long time. She was left with a little permanent damage. Another friend of ours was not treated at all for his Bell's Palsy many years ago when he was in college and his damage was more severe and permanent. My dad had this when he was young and he dd not get treatment and recovered just fine. I guess we are all different and have different immune systems. I hope your friend recovers quickly.
Are the doctos sure your friend did not have a stroke? His symptoms of confusion/disorientation fit stoke better than the palsy. Stroke symptoms are best treated right away also for best results. I hope your friend was not misdiagnosed. A stroke can also cause the drooping face.
Best wishes to you and your friend, bablymers mom
