What could cause the right side of my face to be numb?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Right-sided facial numbness may result from several underlying conditions, most commonly silent sinus syndrome or carotid artery–related issues. Silent sinus syndrome involves gradual collapse of the maxillary sinus, which can compress facial nerves. Carotid artery problems, such as dissection or reduced blood flow, may also disrupt nerve function and trigger one-sided numbness.

Because facial numbness can signal anything from a minor nerve issue to a serious vascular event, identifying the cause quickly matters. A free, instant, online symptom check can help you narrow down possible causes based on your specific symptoms and guide your next steps—whether that's monitoring at home, seeing a specialist, or seeking urgent care.

Explanation

Facial numbness can be caused by several medical issues.

Silent Sinus Syndrome: This is a rare condition where the sinus on one side of the face collapses, which can lead to facial numbness. It is unusual and may not present with typical sinus symptoms like congestion or pain.
Carotid Artery Problems: Issues with the carotid artery, which supplies blood to the face and brain, can also cause facial numbness. This might involve a narrowing of the artery or other changes that affect blood flow.
Numb Cheek-Limp Lower Lid Syndrome: This involves facial numbness and can be associated with other symptoms like a droopy lower eyelid.

If you experience these symptoms, you can check your symptoms with Ubie's free AI-powered tool to better understand potential causes and determine whether you should seek immediate medical attention.
