Suggest Treatment For Pain In Neck

Hi, may I answer your health queries right now ? Please type your query here...Hi, 3 weeks ago I lost my temper and tensed up very tightly. I heard a crunching sound at the bottom of my neck and had very sore muscles in neck, shoulder and back. Muscle pain has eased but the bottom of my neck still hurts at the top of my back, especially when lying down. Worried that I've permanently damaged something, can you help?
