What causes left side tongue numbness and of head feeling fuzzy?

There are many potential causes of left side tongue numbness and feeling of fuzziness in the head. Some of the more common causes include:

* A stroke: A stroke occurs when the blood supply to part of the brain is interrupted. This can lead to a variety of symptoms, including numbness on one side of the body, slurred speech, dizziness, and headaches.

* A transient ischemic attack (TIA): A TIA is a temporary interruption of blood flow to the brain. TIAs are often called "mini-strokes" because they produce symptoms that are similar to those of a stroke, but they are usually temporary.

* Peripheral neuropathy: Peripheral neuropathy is damage to the nerves that control movement and sensation in the limbs. This condition can cause numbness, tingling, and pain in the affected areas.

* Multiple sclerosis (MS): MS is a chronic condition that affects the central nervous system. Symptoms of MS can include numbness, fatigue, vision problems, and muscle weakness.

* A viral infection: Some viral infections, such as the herpes zoster virus (which causes chickenpox and shingles) and the Epstein-Barr virus (which causes mononucleosis), can cause numbness and headaches.

* A brain tumor: A brain tumor can grow and press on the nerves in the brain, causing numbness and other neurological symptoms.

* Migraines: Migraines are severe headaches that can also cause numbness, nausea, and vomiting.

If you are experiencing left side tongue numbness and feeling of fullness of the head, it is important to see a doctor right away. This is especially important if you have any other symptoms that may indicate a stroke, such as slurred speech, dizziness, or weakness on one side of the body.
