Neck pain is a common complaint. Neck muscles can be strained from poor posture — whether it's leaning over your computer or hunching over your workbench. Osteoarthritis also is a common cause of neck pain.
Neck pain can have causes that aren't due to underlying disease. Examples include prolonged straining (looking up or down), sleeping in an uncomfortable position, stress, chiropractic manipulation, or wearing heavy necklaces.
