Hi, Thanks for your query. What you are experiencing is called Radiculopathy . It basically suggests entrapment of a nerve root in your cervical spine in its origin or course. It is somehow not so uncommon now in younger population and we like to call it industrial neck pain, since its prediliction towards people working in computer related industry. It can be caused by lifting weights, episodes of over-exertion during work, long hours on computer, inappropriate posture while sleeping or sitting, lack of proper nutrition-exercises-rest-recreation or any other relevant past medical history. I do hope that you have found something helpful and I will be glad to answer any further query. Take care
