  • What exactly is Bell’s palsy?
    MedlinePlusMay 2026

    Bell's palsy is a condition where the nerve that controls your facial muscles suddenly becomes swollen or inflamed, usually from a viral infection. This causes weakness or paralysis on one side of your face, and it's the most common cause of facial paralysis.

  • Why does my face feel weak or droopy?
    MedlinePlusMay 2026

    The swelling of your facial nerve is pressing on it and preventing it from sending signals to your face muscles properly. This causes the weakness and drooping you're experiencing, and symptoms usually get worst about 48 hours after they start.
