First, stiff neck is actually caused by stiff neck. It's hard, but it's not a big problem. As long as you rest for 1~2 days, you will get better automatically. Therefore, if you wake up and find that your neck feels particularly painful, it is most likely a stiff neck. Everyone just needs to rest quietly at home for a day or two, and pay attention to their posture when they sleep the next night, so there is no big problem.
Second, cervical spondylosis, no matter now for young people or middle-aged people, more or less some people will suffer from cervical spondylosis. Bowing your head for a long time will make you feel particularly uncomfortable in the cervical spine, and there will be nerve compression around you. Every time I squat for too long, I feel particularly dizzy in the end. In particular, some young people especially like to play mobile phones. If you keep your head down for a long time, you will get cervical spondylosis, so everyone must adjust their daily routine and habits.
Third, myofascitis Because of some people's working conditions, they must wait in a cold place for a long time, which will lead to myofascitis. Therefore, everyone must pay attention to keep warm at ordinary times and don't catch a cold, otherwise it will make the condition worse. If you don't feel better, you should go to the hospital to consult a doctor in time. After all, they have rich experience and medical knowledge. Don't listen to some gossip, or you may make your illness worse, and you will regret it then.
