Im having a lot of lower abdominal pressure and pressure in  my rear..that is very unconfortable ...few days ago I was involved in car accident was rear ended. I went to the ER and they did a CT Scan with blue dye..but they said everything was ok but I still have that pain is that normal??.
Hi. It is possible the scan done immediately after accident can be normal in many cases. IT will depend upon the clinical examination by Doctor that whether this is just because of post-traumatic heaviness or a problem with the spine causing lower abdominal pressure contusion in lower abdomen. If you do not have any other symptoms like black stools, bloating, nausea, vomiting, urinary symptoms or pain in lower limbs, you can wait and watch. If any of the symptoms are present I would advise such a patient to undergo a clinical examination and investigations like repeat/ review CT scan and other tests.
