<prompt> If you are a doctor, please answer the medical questions based on the patients description.I had an hsg 3 days ago. The cramping was tough during the procedure but very mild once it was over. However, the last 2 days I have been terribly bloated, to the point I cant sleep and my abdomen is so distended. It looks like I swallowed a basketball. I am so uncomfortable. Any thoughts?  <response>: Hi. Thanks for your query.SG- hysterosalpingography is a procedure in which the dye is pushed into the uterus through a canola put into the uterus. The possible cause for distension can be a reaction to the dye or perforation of the uterus and trauma to the intestines. -You need to visit ER get admitted -Be nil orally - do not take anything orally.-get investigated by :Standing X-ray abdomen, ultrasonography, Ct scan.-Follow the advice of the Doctors. The treatment will depend upon the findings on investigation.
