Do you feel lightheaded often? Doctor says this lesser-known neck factor might be the culprit

Frequent dizziness or lightheadedness can often be linked to an overlooked neck muscle called the sternocleidomastoid (SCM). This muscle helps control head movements and sends critical signals to the brain about head position, which the balance system relies on. Imbalances or spasms in the SCM can confuse these signals, leading to dizziness. Simple exercises to release and strengthen the SCM may help improve balance, but persistent or severe dizziness should be evaluated by a healthcare provider.
