Some causes of neck pain and numbness include strain, tension, accidents and trauma, according to MedlinePlus. Other causes of neck pain include medical conditions, such as fibromyalgia, fractures of the spine, sprains, infections and cancer.
Treat minor neck pain and numbness at home by using over-the-counter pain relievers, ice for up to 72 hours and then heat, explains MedlinePlus. Rest and stop normal activity for a couple of days and then start doing range-of-motion exercises slowly, which helps to stretch the muscles of the neck. Massage can help as can sleeping on a special neck pillow, which is available from pharmacies and retail stores. A doctor may prescribe a neck collar to relieve discomfort, too.
If the symptoms of neck pain do not improve within a week, see a medical professional, advises MedlinePlus. Also see a doctor if neck pain is present along with tingling, numbness or weakness in the hand or arm, the pain occurs after a fall or other injury, or if there are lumps or swollen glands in the neck. Contact a doctor if experiencing neck pain with difficulty swallowing or breathing, if the pain gets worse when lying down or at night, if there is loss of bowel or bladder control, or if there are issues with balance or walking.
