Whether or not a tubal is painful varies from person to person. If the fallopian tubes are patent, the patient usually does not feel anything, i.e., no pain. If the fallopian tubes are not open, there is a possibility of pain. The most common method to pass the fallopian tube is to use tubal lavage. Generally, pushing 20ml of saline without resistance and without any discomfort or pain to the patient means that the tube is open. If the saline is pushed in reluctantly and only a few milliliters are pushed in and resistance is felt, the pressure continues to rise, the patient feels distension and pain in the lower abdomen, and in some cases the pain is very obvious, and the fluid flows back into the syringe, it indicates a blockage in the fallopian tube. If the fluid cannot be pushed in even with pressure during the pushing process, reflux will occur and patients with completely blocked tubes may not have pain. If during the pushing process, the patient is able to push smoothly after the pressure injection and the pain is mild and then relieved, it means that the adhesions have been separated by saline, which has a certain therapeutic effect, and the patient is in mild pain at this time.
