I feel dizzy and pain in the right side of my neck while moving through sleeping on my right side im worry that there is a problem in my arteries ?

Muscle spasm: 20's female w. unilateral neck pain has dizziness w. change in position. These symptoms are associated with superior trapezius muscle spasm. A 20's person would not be expected to have arterial compromise. Best doctor to diagnose is an Osteopath. Massage, heat. topical cannabinoids, and biofeedback are therapeutic. Benzodiazepines can benefit, but are attendant with dependency and side effects.
