What causes pain in the lower abdomen on both sides extending to the upper thigh roots?
Disease description:
My older sister says she is experiencing pain on both sides of her lower abdomen extending to the upper thigh area. She doesn't know whether it's caused by intense physical activity yesterday. May I ask what might cause pain on both sides of the lower abdomen extending to the upper thigh area?

Causes of pain on both sides of the lower abdomen extending to the upper thigh roots include:
1. Muscle and ligament injuries: Strenuous exercise or accidental sprains may cause strains of the muscles and ligaments in this area, leading to pain.
2. Hip joint problems: Such as hip synovitis, which may result from prolonged physical strain or exposure to cold, causing edema, inflammation, and fluid accumulation in the hip joint synovium, thus inducing pain.
3. Inguinal lymphadenitis: When soft tissue infections occur on the lower limbs, bacteria may travel via lymphatic fluid back to the inguinal lymph nodes, causing lymph node swelling and inflammation, which leads to pain.
4. Gynecological diseases: In women, gynecological inflammations such as pelvic inflammatory disease (PID) and adnexitis may also cause pain in the lower abdomen and upper thigh regions.
5. Others: Conditions such as gastrointestinal issues (e.g., intestinal cramps, gas accumulation), and urinary system diseases (e.g., urinary tract infections, prostatitis) may also cause similar symptoms.
