Hi, Thank you for your question. Generally, shoulder and arm numbness originates from the neck problems due to irritation in the cervical (neck) spine because the nerves that supply the back of the head start in the upper cervical spine. Mostly, these symptoms aggravate after turning head and typically occur in patients with previous neck injuries and in patients with marked arthritis of the upper cervical spine. In addition, this pain exacerbate with prolonged sitting in a stooped posture and when working on a computers for long hours. If you suffer continuous numbness, please arrange an appointment with a neurologist right away who will evaluate the possibilities here and can provide you an appropriate treatment. Hope this information proves helpful to you. Take Care & Regards!!!
