The so-called periarthritis of the shoulder is a sterile inflammation of the shoulder region caused by overexertion, straining stimuli, exposure to cold, or external injuries. It is primarily characterized by pain around the shoulder, especially during shoulder lifting, where the pain becomes more pronounced and can seriously affect the patient's normal shoulder-lifting function. This condition often occurs in middle-aged and elderly patients. Common treatments for periarthritis of the shoulder include rest and protection, local heat application, and local injection treatment for specific pain points. Additionally, topical ointments that invigorate blood and dissipate stasis can be used, along with oral non-steroidal anti-inflammatory and analgesic drugs to alleviate the patient's pain symptoms.
