Pain after ultrasound examination, such as a short period of pain does not need to continue the examination, can be observed first; if the pain is serious or lasts a long time need to do abdominal ultrasound and gynecological examination. Pain during ultrasound examination may be caused by improper operation or too rough, resulting in abrasion of the vaginal mucosa, thus causing pain. It is also possible that the probe touches the cervix during the examination, stimulating the uterus to spasmodic contractions and causing pain in the abdomen. Generally, the pain is mild and will improve on its own within a short period of time, so there is no need for special examination and it can be observed for the time being. However, if the pain is severe or lasts for a long time, it may be caused by vaginal inflammation or endometriosis, etc., which stimulates the vaginal mucosa or the ultrasound probe touches the ectopic nodules during the examination. In this case, it is necessary to go to the hospital in time to improve the gynecological internal diagnosis, as well as abdominal ultrasound and other examinations, to diagnose the specific causes of pain and then give symptomatic treatment.
