Usually affecting one side of the face, Bell's palsy is a sudden, brief weakening or paralysis of the facial muscles. It starts when the facial nerve, in charge of facial expressions, gets swollen or squeezed. Viral diseases like herpes simplex are often linked to it, but the exact origin is unknown. Typical symptoms include drooping on one side of the face, trouble shutting the eye, drooling, loss of taste, and enhanced sensitivity to sound in the impacted ear.
Bell's palsy strikes quickly and usually peaks in 48 hours. Though concerning, the disorder is typically not permanent. Most patients fully recover in a few weeks to several months, especially with early therapy. Corticosteroids are often prescribed to lower nerve irritation. Furthermore, helping to rebuild muscle strength and coordination are face exercises and physical therapy.
Early diagnosis and treatment raise the possibility of full recovery. Particularly if blinking is compromised, eye care is vital to avoid dryness or damage. Although Bell's palsy can strike anyone, those with diabetes or upper respiratory problems are more likely to get it. Reducing the risk could depend on good immune system and stress management. Though it starts suddenly, Bell's palsy is usually a self-limiting and treatable disorder.
