Bell's palsy is essentially an inflammatory reaction, but this inflammation is a nonspecific type. It also exhibits the typical inflammatory symptoms of redness, swelling, heat, and pain. However, this inflammation is not caused by direct infection from viruses, bacteria, or fungi. Since Bell's palsy is an inflammatory condition, its treatment must include corticosteroids for management. Additionally, administration of B vitamins is necessary to promote nerve function recovery. Moreover, targeted rehabilitation exercises, acupuncture, and local physiotherapy from the rehabilitation department also play a vital role in the recovery from Bell's palsy. Generally, with proper and timely treatment, Bell's palsy can fully recover, and most patients will not experience any impact on their future quality of life. However, if the symptoms of Bell's palsy are very severe, and the patient has a history of diabetes, the prognosis may be poorer.
