Pain in the middle of the right side of the back is mainly due to strain and cold in the scapularis raphe, rhomboid and rhomboid muscles in the back, resulting in inflammation and pain. The following measures are available for treatment: 1. The back must be kept strictly warm and must not get cold. 2. There must be support at the elbow joints bilaterally when sitting in order to keep the muscles in the back in a fully relaxed state. If no support is provided, it will only lead to further aggravation of the strain injury. In the standing position, try to put your hands into your jacket pockets, which can also play a supporting role to keep the back muscles relaxed. 3, you can go to the hospital acupuncture and massage department, acupuncture and massage treatment. The main focus of the massage is on manual flicking, which effectively loosens the local adhesions and relaxes the muscle tissue, helping to relieve pain.
