Bell’s palsy makes the facial muscles temporarily paralyzed or weak. It is caused due to conditions such as viral infection, etc. In addition, bell’s palsy will cause inflammation and swelling of the facial nerve (the 7th cranial nerve).
Faces of the people with the disorder will droop on the right side or both sides. In some cases, they may have a lopsided smile or an eyelid that won’t close. These effects last for several months and fade away without treatment. However, in rare cases, the effects can last forever.
