Bell's palsy is one type of facial nerve paralysis. The 7th cranial nerve controls the muscles of the face, and although scientists do not know the exact cause of Bell's palsy, they think it may be due to nerve damage from an infection, for example, the flu, common cold viruses, and more serious infections like meningitis. The symptoms of Bell's palsy vary from person to person, but can include:
- Mild weakness to total paralysis
- Dry eye
- Dry mouth
- Eyelid drooping
- Mouth drooping
- Dry mouth
- Changes in taste
- Excessive tearing in one eye
