In clinical practice, patients with sudden cramps in the neck are mostly patients who have been in one position for too long while sleeping or have been cold in the neck for a long time, causing the sternocleidomastoid muscle to be in a contracted, tense state, which produces localized spasmodic pain with cramping, and there is also restricted movement of the neck. Patients with acute attacks of cervical spondylosis may also have localized cramps and radiating tingling pain in the upper extremities, decreased skin sensation in the upper extremities, decreased muscle strength, and impaired finger dexterity. Patients with interspinous ligamentitis of the neck, localized bursitis, or disorders of the small joints of the cervical spine can produce cramps. Therefore, after the patient has developed this phenomenon, the disease needs to be clarified and treatment given, which can alleviate this phenomenon.
