Simply put: don't go for an injection. This medicine is unknown and unsafe. Massage and massage are the same, but the words are different. Don't expect to root out the root causes. Nothing in the world can be cured. You caught a cold today, but you can't cure it if you come back next year. You can't stand the cold, but you have such high requirements for massage. Your problem is called neck and shoulder fatigue syndrome. You can go to the hospital for an X-ray to see if there is anything wrong with the bone. If the X-ray is normal, do it.
