Hip pain after intercourse is generally due to the following common causes: i. Patients have been intercourse for too long, which can cause a large amount of energy consumption in the body. It is also accompanied by the accumulation of lactic acid as well as metabolic waste in the hip muscles, which can cause soreness and pain symptoms. At this time, it is recommended that patients take adequate rest, eat a high sugar and high protein diet to replenish energy, and take a bath in warm water. The painful area of the hip can be applied externally with hot ointment packs or fumigated with moxibustion strips, and appropriate massage to promote the metabolism of lactic acid can relieve the pain of the hip more quickly. Second, if the amplitude of the patient is too large during intercourse, it may cause muscle strain at the hip, and the pain is often more intense. If the symptoms are serious, a local hematoma may even be formed, affecting the normal activities of the patient. Patients are advised to go to the hospital as soon as possible to improve the ultrasound examination. If there is a hematoma formation, it is necessary to perform hematoma debridement and drainage to avoid inducing infection.
