What causes the left side of your head to get numb or tingle?

Numbness or tingling on the left side of the head can have several potential causes. Here are a few possible reasons:

1. Cervical Spine Issues: Problems with the cervical spine, such as a pinched nerve or herniated disc, can compress nerves and cause numbness or tingling in the head and neck region.

2. Migraines: Migraines are severe headaches that can cause various neurological symptoms, including numbness and tingling on one side of the head.

3. Trigeminal Neuralgia: This condition is characterized by intense pain in the face and can also cause numbness or tingling in the affected areas.

4. Multiple Sclerosis (MS): MS is a neurological condition that affects the central nervous system and can cause a variety of symptoms, including numbness and tingling in different areas of the body, including the head.

5. Stroke: A stroke occurs when the blood supply to a part of the brain is interrupted. If the stroke affects the left side of the brain, it can lead to numbness or tingling on the left side of the body, including the head.

6. Transient Ischemic Attack (TIA): A TIA is a temporary interruption of blood flow to the brain and can cause symptoms similar to a stroke, including numbness or tingling on one side of the body, including the head.

7. Brain Tumors: In rare cases, a brain tumor can press on nerves and cause numbness or tingling in different areas of the body, including the head.

8. Peripheral Neuropathy: This condition affects the peripheral nerves and can cause numbness, tingling, and other sensations in different areas of the body, including the head.

9. Diabetes: Poorly managed diabetes can lead to nerve damage (diabetic neuropathy) and cause symptoms like numbness and tingling in various body parts, including the head.

10. Certain Medications: Some medications have side effects that can include numbness or tingling, which may affect one side of the head.

It's important to consult a healthcare professional if you experience persistent or sudden onset of numbness or tingling on one side of your head, especially if accompanied by other symptoms or concerns.
