<s>[INST] A tearing sound in my neck woke me up last night, and I have had terrible pain on that side of my neck since - it has kept me in bed all day barely able to move. At times it feels like the muscle is tightening up and causes shooting pain. I have been taking Excedrine and alternating ice and heat. What could this be and what should I do for it? [/INST] Hellowelcome to Chat Doctor, i had gone through your history and when I found such type of patients in my clinic, I was treating them with following treatment take hot water fomentation twice a day for 20 minutes minimum massage with pain reliever oil which increases the blood circulation and nutrition supply do gentle exercise of neck to maintain the range of motion. Bending forward and backward, bending sideways. Do not rotate your neck do isometric exercises of the neck use thin pillow for sleeping do not bend your back too much thank you I think this may help u </s>
