What could cause tingling on the left side of my neck and face?

Tingling in both the neck and face on one side often suggests involvement of nerves that serve those areas. Some common causes include:

Compressed or irritated nerves: Nerves in the neck (cervical spine) can become compressed due to posture, injury, or herniated discs, which may cause tingling that spreads to the face. Trigeminal or cervical neuropathy: Irritation or dysfunction of these nerves can produce tingling on one side of the face and neck. Shingles (herpes zoster): This viral infection can cause tingling or burning pain on one side before a rash appears. Migraine with aura: Some people experience tingling or numbness before or during a migraine. Multiple sclerosis or other neurological conditions: These can affect nerve signals and produce tingling sensations. Anxiety or stress: Tension in the neck and face muscles, combined with hyperventilation, can cause tingling sensations. If tingling is persistent, worsens, or is accompanied by other symptoms like weakness, trouble speaking, or a rash, it’s important to seek medical attention to determine the cause and appropriate treatment.
