Abdominal pain after tubal imaging may be caused by tubal incompatibility, too much force in operation movement, uterine contraction and so on. 1. Tubal opacity: Hysterosalpingography is a method used to check the tubal opacity, and it is also able to understand the location of the blockage and the shape of the uterine cavity. When the fallopian tube is not patent, it can cause pain in the lower abdomen after injecting contrast medium. 2. Excessive force during operation: Excessive force during contrast injection can cause spasm of fallopian tube and abdominal pain. X-ray fluoroscopy can show that the uterine horn is rounded and the fallopian tube is not visible, so it can be injected with atropine according to the doctor’s instruction, and then observed by fluoroscopy after 20 minutes. 3. Uterine contraction: the process of inserting the contrast tube into the uterine cavity and injecting the contrast medium may cause damage to the uterine lining, resulting in uterine contraction, which may also cause abdominal pain. For serious cases, it is recommended to seek medical advice to clarify the cause and provide targeted treatment.
