What to do if i have a really bad neck pain?

Some things to try: Use a heating pad. Place a towel behind your head or under chin and have someone pull gentle traction, change your pillow - try several until you find the one that's most comfortable for you. Use nsaid's (ibuprofen/naproxen) at the first sign of pain before it gets really bad.

Anti-inflammatory: Neck pain usually comes from a degenerative joint or disc. Sometimes it's from a muscle strain or sprain. Early treatment options include a short course of nsaids (advil, aleve), gentle massage, moist heat, and focusing on posture. If pain lasts greater than 2 weeks see your physician.
