The symptoms of soreness in the muscles of the back of the shoulder are mainly due to excessive local exercise, which leads to the accumulation of metabolites and stimulation, resulting in the symptoms of soreness. It may also be due to local injury and strain, resulting in an inflammatory response, leading to soreness and pain. The pain can be relieved by local brake rest, anti-inflammatory and analgesic treatment, and blood circulation and blood stasis treatment. Local rest is to prevent further aggravation of the injury or metabolic products from being removed and excreted in a timely manner, resulting in prolonged symptoms. Anti-inflammatory and analgesic drugs can often be used, such as fenbendazole and celecoxib for oral use and fotarolimus emulsion and loxoprofen sodium gel for topical use. In addition, oral medications can be used to activate blood circulation and remove blood stasis, such as Tongluo Kaiqiao Tablets and Bone Injury Recovery Pills, and topical medications such as Yunnan Baiyao Aerosol and Jinhuang Paste can be used to activate blood circulation and remove blood stasis. Local heat treatment such as hot compresses, spectrum irradiation, moxibustion, etc. can also be used to relieve the pain. Generally speaking, with rest and the above treatment, the symptoms can be relieved within a week or so, if the symptoms are not relieved for a long time, seek medical attention.
