Performance of the stiff neck
I don't know if you have had an experience. You slept well at night. When you woke up in the morning, you found that your neck was licking, and the back of the neck was sore. It took several hours to ease.

It refers to a disease in which the muscles on one side of the neck are paralyzed, causing neck pain and limited activity. The professional diagnosis is called "acute cervical vertebra joint inflammation" or "neck and shoulder muscle fasciitis".
