After intercourse, pain in the lower abdomen is clinically recommended to do hot compresses or moxibustion. The most common clinical cause of this condition is caused by chronic inflammation of the pelvis. When there is chronic inflammation in the pelvis, the elasticity of the tissues will be reduced, and after intercourse will cause pelvic congestion, so there will often be pain in the lower abdomen. In clinical practice, you can go to the hospital for ultrasound and gynecological examination, the purpose of which is undoubtedly to exclude the possibility of pelvic tumor. In the case of endometriosis, such as the local formation of chocolate cysts, or in the case of clinically formed larger ectopic masses, it can also cause pain in the lower abdomen after intercourse. In addition, if there is a large pelvic tumor, it may also cause pain in the stomach after intercourse. In clinical practice, according to the results of ultrasound examination, appropriate treatment should be given, either surgical treatment or conservative treatment is needed in clinical practice.
