Is vertigo related to the vagus nerve?
Noninvasive Vagus Nerve Stimulation Shows Promise for Acute Vestibular Migraine. As vestibular migraine is a common cause of vertigo, the results, which need to be confirmed with larger studies, suggest some potential for an effective and easy to use treatment for patients.
How do you fix a vasovagal response?
Isometric contractions of the muscles of the arms, hands, feet, and legs can stop the vasovagal reaction immediately and prevent fainting. Contracting these muscles pushes blood back into the center of the body, interrupting the reflex, and stopping it from progressing to loss of consciousness.
