Suggest Remedy For Constant Neck Pain

Hello, am 35 years old male - have been suffering from neck pain. It's sever in the morning after I wake up. The pain is on the left-side upper neck and is towards the shoulders. Recently had been through physiotherapy and got ultra-sound done. I am also on CCM tablets. Its been a week I have stopped taking CCM tablets and now the pain has increased. Am not able to reduce the pain. My profession requires me to work a lot on computer and it demands physical exercise. Please advice should I continue with CCM tablets and what are the other precautions I should take.
