Tubal imaging is particularly painful and does not show up, most often considered to be a blockage of the fallopian tubes. In the process of tubal imaging, the contrast medium does not show up in the fallopian tube, suggesting that the contrast medium does not pass through the fallopian tube, and tubal blockage is usually considered. Tubal blockage usually has no obvious symptoms, but during tubal imaging, the fallopian tubes will not be unblocked and the contrast medium will not be able to flow out of the fallopian tubes, causing it to accumulate in the uterine cavity, resulting in increased pressure in the uterine cavity, and thus obvious pain. And most tubal blockages are secondary to infection, especially pelvic inflammatory disease. In addition, tubal blockage can also be caused by foreign body reaction due to a variety of foreign objects, surgical injuries, endometriosis, congenital tubal malformations, and so on. However, other factors cannot be ruled out. Patients are advised to take further examination to clarify the cause, as this symptom may directly cause infertility.
