Strain, cervical spondylosis and exogenous diseases can be treated with Guizhi and Gegen decoction. Ramulus Cinnamomi (6g), Radix Paeoniae Alba (6g), Rhizoma Zingiberis Recens (9g), Radix Glycyrrhizae Preparata (6g), Fructus Jujubae (3 pieces) and Radix Puerariae (12g). Guizhi Jiagegen Decoction is characterized by exogenous wind and cold, the sun's meridian qi is not comfortable, the body fluid can not be fully distributed, and the meridians are blocked. But when sweat comes out of the wind, it is superficial deficiency. Therefore, Guizhi decoction is used to reduce the dosage of Cinnamomum cassia and Paeonia lactiflora, and Pueraria lobata is added to relax muscles and tendons.

I can't massage. I can try cupping and scraping.
