Symptoms of Facial Palsy

The symptoms of facial palsy are many and vary from person to person. The symptoms will depend on the cause of your facial palsy and here we discuss some of the more common symptoms experienced.

How quickly do symptoms occur?

The onset of your symptoms may be sudden (appearing overnight), or may appear over two or three days. Alternatively your symptoms may develop slowly over time (over weeks, or even months). In either situation you should visit your GP as soon as possible, as further investigations may be required. It is important that you have a clear diagnosis of the cause so that you are given the correct treatment and advice.

What are the symptoms of facial palsy?

  • Facial palsy normally affects only one side of the face although in rare cases it may affect both sides. It does not cause weakness in your arms or legs. If you experience weakness in your arms or legs as well as weakness on one side of your face, you should seek immediate medical attention. These symptoms grouped together may indicate a stroke.
  • A complete facial palsy on one side of the face affects the brow, eye, cheek and mouth. This means the facial nerve signals that control movement in these muscles are not working. The face may appear flattened and movement may be lost.
    Symptoms may improve or worsen over time depending on the type and degree of facial nerve damage and the cause of your facial palsy.
  • Some types of facial palsy will affect sensation including pain, as well as facial movement. This may mean that the nerve which is responsible for sensation (trigeminal nerve) has been damaged as well as the facial nerve. The facial nerve controls movement, tear production, saliva production and taste.
  • Loss of sensation may mean you cannot feel your face when you touch it.
  • Inability to blink or close the eye is a common symptom and needs prompt attention from your GP.
