Bell's Palsy

Parálisis de Bell

What it means

Bell's palsy is a disorder of the nerve that controls movement of the muscles in the face, called the facial or seventh cranial nerve. Damage to this nerve causes weakness or paralysis of these muscles, and Bell's palsy is the most common cause of facial paralysis. It usually affects just one side of the face. Symptoms most often start suddenly and may range from mild to severe; they include twitching or weakness of the muscles in the face, drooping of the eyelid or corner of the mouth, drooling, and difficulty closing one eye. It is thought to be due to swelling (inflammation) of the facial nerve, and the cause is often not clear. Most people begin to get better within 2 weeks. MedlinePlus says to contact a provider right away if the face droops, because the provider can check for other, more serious conditions, such as a stroke.

Your right to an interpreter in the United States

If English is not your primary language and you have difficulty communicating in English, you may need an interpreter or a translated document when you visit a doctor or dentist, go to the emergency room or pick up a prescription. The U.S. Department of Health and Human Services Office for Civil Rights states that two federal laws, Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act, require programs that receive its funding to provide language access services free of charge.

You can ask when you make the appointment or at the front desk: "I need an interpreter, please." «Necesito un intérprete, por favor.»
