What is neck spasm?

A neck spasm is sudden tightness and pain in your neck muscles. A spasm may be caused by some activities or repeated movements. For example, you may be more likely to have a neck spasm if you slouch, paint a ceiling, work at a computer, or sleep with your neck twisted. But the cause isn't always clear.

Home treatment includes using heat or ice, taking over-the-counter (OTC) pain medicines, and avoiding activities that may lead to neck pain. Gentle stretching, or treatments such as massage or manipulation, may also help ease a neck spasm.

For a neck spasm that doesn't get better with home care, your doctor may prescribe medicine. The doctor may also suggest exercise or physical therapy to help strengthen or relax your neck muscles.

• Try heat or ice, whichever feels better. Apply it for 10 to 20 minutes at a time, several times a day. Put a thin cloth between the heat or ice and your skin. You might also try switching between heat and ice.
• Ask your doctor if you can take acetaminophen (such as Tylenol) or nonsteroidal anti-inflammatory drugs, such as ibuprofen or naproxen. Your doctor can prescribe stronger medicines if needed. Be safe with medicines. Read and follow all instructions on the label.

• Stretch your muscles every day, especially before and after exercise and at bedtime. Regular stretching can help relax your muscles.
• Try to find a pillow and a position in bed that help improve your night's rest.
• Try to stay active. It's best to start activity slowly. If an exercise makes your pain worse, stop doing it.
