For women, back pain is a very common phenomenon in ordinary life. If a woman always has back pain and her waist is normal, it is likely to be caused by gynecological diseases. The following gynecological diseases can cause back pain in women: 1. Pelvic inflammatory disease. Pelvic inflammatory disease refers to inflammation of the female reproductive organs, connective tissue around the uterus and the pelvic peritoneum. Some women also have symptoms such as increased leucorrhea, local itching and tingling. 2. pelvic tumors. If there are tumors in the pelvis, such as fibroids, cervical cancer, endometrial cancer, etc., when the tumor compresses the nerves or the cancer cells infiltrate into the pelvic connective tissue, low back pain can occur. 3. Abnormal position of the uterus. The normal position of the uterus is anteversion and forward flexion. Some women who have had too many births and too many abortions and have poor recovery can also cause low back pain. If you have back pain, it is recommended to go to the hospital for examination and treatment so as not to delay the condition.
