Second, due to the back of the head location of the cold, such as wearing a low collar, window convection and blowing air conditioning fan, etc., may lead to a drop in local temperature, causing a drop in blood circulation, so the metabolites produced will appear to increase the accumulation of peripheral nerve stimulation pain, so after this situation should keep the cervical spine relaxed, try to choose a seat with a backrest, and The pillow should not be too high, must do a good job to keep warm, more warm water bags for hot compresses.
