Facial Numbness After Waking: Possible Causes and When to Seek Help - Neurology

More Info

---

Facial numbness, especially when it occurs after waking up, can be concerning and may have various underlying causes. The symptoms you describe—numbness around the left eye, forehead, temples, and cheekbone—are particularly notable, especially since they are more pronounced in the morning and can last for about 30 minutes. The additional symptom of a small, painful bump behind your left ear with a red center raises further questions about the nature of your condition.


Possible Causes of Facial Numbness
1. Nerve Compression: One common cause of facial numbness upon waking is nerve compression. This can occur due to sleeping positions that put pressure on the facial nerves, particularly if you sleep on your side. The numbness may be transient, resolving once you change positions or get up.

2. Cervical Issues: Problems in the cervical spine, such as herniated discs or cervical spondylosis, can lead to nerve compression that manifests as facial numbness. This is particularly relevant if you experience neck pain or stiffness.

3. Migraines: Some individuals experience aura symptoms, including numbness or tingling in the face, as part of a migraine episode. If you have a history of migraines, this could be a potential explanation.

4. Multiple Sclerosis (MS): While less common, MS can cause facial numbness due to demyelination of nerves. This is usually accompanied by other neurological symptoms, so it would be important to consider your overall health and any additional symptoms.

5. Infections or Inflammation: The small, painful bump behind your ear could indicate an infection, such as a lymph node reacting to an infection or inflammation in the area. This could potentially be related to the numbness if there is an underlying inflammatory process affecting the nerves.

6. Bell's Palsy or Facial Nerve Issues: If there is any history of facial nerve issues, such as Bell's palsy, it could lead to numbness or altered sensations in the face.


When to Seek Help
Given that your symptoms have persisted for a month and you are experiencing additional symptoms (the painful bump), it is advisable to seek medical attention. You should consider consulting a healthcare provider who specializes in neurology, as they can perform a thorough evaluation of your symptoms and medical history. They may conduct neurological examinations and possibly imaging studies (like an MRI) to rule out any serious conditions.


Recommended Specialists
1. Neurologist: A neurologist can assess your facial numbness and any associated symptoms, providing a comprehensive evaluation of your neurological health.

2. Ear, Nose, and Throat (ENT) Specialist: Given the bump behind your ear, an ENT specialist can evaluate any potential infections or issues related to the ear and surrounding structures.

3. Primary Care Physician: If you are unsure where to start, your primary care physician can evaluate your symptoms and refer you to the appropriate specialist.


Conclusion
Facial numbness can arise from various causes, ranging from benign to more serious conditions. The combination of your symptoms—facial numbness upon waking and a painful bump behind your ear—warrants a medical evaluation to determine the underlying cause and appropriate treatment. Early intervention can lead to better outcomes, so do not hesitate to seek help from a qualified healthcare professional.
