Pain in the back of the neck after long-term computer use is due to long-term chronic strain on the cervical spine and neck and shoulder muscles. The long-term straightening and forward flexion of the neck will lead to continuous tension in the cervical spine and neck and shoulder muscles, resulting in strain injury, which will produce an inflammatory response leading to poor local blood circulation and accumulation of metabolites, resulting in painful symptoms. In this case, the first thing to do is to change bad habits, when working with your head down for a long time, you should get up after 45 minutes. You can raise your head and look into the distance, or you can do the little swallow flying movement and do the neck mitzvah, which can relieve the neck strain. If the symptoms are obvious, you can take oral non-steroidal anti-inflammatory drugs, such as diclofenac and celecoxib, which can clearly relieve local inflammation and reduce the symptoms of pain. Physical therapy such as traction, massage, tui na, acupuncture, hot compresses, moxibustion, etc. can be used in combination to relieve the symptoms.
