After sexual intercourse, lower abdominal pain, what medical examinations should be done at the hospital??

Patient's question:

Doctor
After having sex with my friend, I've been experiencing pain below the navel, and it seems to be related to an issue in the uterus. I want to know what specific tests I should undergo at the hospital. Thank you!

Doctor's answer:

??????Hello, lower abdominal pain during intercourse may be due to the potential damage to the vaginal mucosa of a woman during intense sexual activity, which can cause discomfort or even vaginal pain during intercourse. Lower abdominal pain during intercourse may suggest the possibility of pelvic inflammatory disease. The symptoms of pelvic inflammation often include lower abdominal dull pain, abdominal tenderness upon palpation, and discomfort or unease in the reproductive tract during gynecological examinations. In acute cases, symptoms may include fever, abdominal muscle tension, pain and resistance to pressure, and general fatigue. If you experience lower abdominal dull pain, it is recommended to visit a hospital for examination to check for gynecological inflammation. Generally, there are two reasons for lower abdominal pain after intercourse: physiological and pathological.
Physiological: During intercourse, the thrusting of the male penis can cause intense stimulation to the female vagina, abdominal cavity, and pelvic organs, leading to rapid breathing and involuntary muscle contractions in the female body, which may cause pain.
Pathological: Consider conditions such as endometriosis or pelvic inflammatory disease. It is recommended to visit a hospital for an ultrasound examination to assess the condition of the uterus and adnexa. Based on the specific results, appropriate treatment measures should be taken.
