Pain on the left back side of my head/neck

Hi,
   Since 1 year I'm getting pain on the left back side of my neck and head. At time my whole left side of the body seems to be numb. I consulted some doctors. They took some X-Rays and suggested not to drive any kind of vehicle but I couldn't stop as I need to drive to my office daily. I could have neglected this but its affecting my daily tasks. The pain is disturbing me and not allowing me concentrate on any thing. I also observed that I'm suffering from hyper tension since I started suffering from this disorder. Please anyone suggest me what kind of problem I'm facing and what medication I should take.

Hi, Thank you for your question. Generally pain in the back portion of the head 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, this kind of head pain aggravates after turning head and typically occurs 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.  On the other hand, there are patients who experience similar pain with sinusitis (sinus with infected mucus) and migraine. If you suffer continuous pain at back of head, please arrange an appointment with a neurologist right away who will evaluate the possibilities here and can provide you an appropriate treatment. Hope it helps.
