Bell’s palsy<\/strong> is a neurological condition that causes sudden, temporary weakness or paralysis of one side of the face. It occurs when the facial nerve (cranial nerve VII) becomes inflamed or compressed, disrupting signals to facial muscles.<\/span><\/p>\n

Symptoms typically develop rapidly \u2014 often within hours \u2014 and can be alarming. Although Bell\u2019s palsy can be distressing, it is usually not life-threatening. Most people recover fully within weeks to months, especially with early treatment. It is different from conditions like stroke or vertigo, though sudden facial weakness always requires urgent medical evaluation to rule out serious causes.<\/span><\/p>\n
