I have pain in my neck?

Vague: Unfortunately your symptom is pretty vague. You need to provide more information like duration, persistent or not, anything that flares it, any thing that relives it and so on and so forth...

Spine Specialist: Neck pain can be due to a number of conditions, from muscle strain, to pain from the joints (facet joints), to pain from the discs, and if it radiates down the arm, can be from nerves. See a spine specialist (physiatrist, orthopaedist).

See Doctor: First try nsaids like ibuprofen, aleve and you can even add some tylenol (acetaminophen) to help with pain. Ice the area for 20 min at a time and see if these help reduce the pain. If this persists longer than a few days, consider seeing your doctor for stronger medications to help. Typically most people get better within a few weeks of an injury. If not better consider further imaging studies to evaluate.

Several reasons: Could be muscle problem, nerve root irritation, bad mother-in-law. Sorry couldn't resist. I love my mother-in-law. Maybe time to see your doc for it to be evaluated.

Heat: I am not sure of the source of your pain or it's chronicity. I see that you are already taking Ibuprofen which can be a good choice. You can also consider warm shower against neck or heating pad (ensure you don't get burned). Acupuncture can be very helpful for relief of neck pain. If pain is too severe or is not resolving, medical assessment would be prudent.

Neck pain: Neck pain can be from strained muscle, mis-alignment, nerve impingement. For acute neck pain try ice and anti inflammatory. If persisting see your physician.
