Bell S Palsy
Bell’s palsy is a condition in which the muscles on one side of your face become weak or paralyzed. It affects only one side of the face at a time, causing it to droop or become stiff on that side.
It’s caused by some kind of trauma to the seventh cranial nerve. This is also called the “facial nerve.” Bell’s palsy can happen to anyone.
Bell's palsy occurs when the seventh cranial nerve becomes swollen or compressed, resulting in facial weakness or paralysis. The exact cause of this damage is unknown, but many medical researchers believe it’s most likely triggered by a viral infection.
The viruses that have been linked to the development of Bell’s palsy include:
Herpes simplex, which causes cold sores and genital herpes
HIV, which damages the immune system
Sarcoidosis, which causes organ inflammation
herpes zoster virus, which causes chickenpox and shingles
Epstein-Barr virus, which causes mononucleosis
The symptoms of Bell’s palsy can develop one to two weeks after you have a cold, ear infection, or eye infection. They usually appear abruptly, and you may notice them when you wake up in the morning or when you try to eat or drink.
Bell’s palsy is marked by a droopy appearance on one side of the face and the inability to open or close your eye on the affected side. In rare cases, Bell’s palsy may affect both sides of your face.
Other signs and symptoms of Bell’s palsy include:
difficulty eating and drinking
an inability to make facial expressions, such as smiling or frowning
muscle twitches in the face
dry eye and mouth
Sensitivity to sound.
