Brief Answer:
yes
Detailed Answer:
yes if the pain is severe in the right side of the abdomen you should definitely go back. They can't diagnose IBS from just having a normal CT and labs. Obviously a physical exam needs to be done to see if the pain is muscular in origin or something inside the abdomen.
Depending on where exactly is the pain, it could be many different things. If it is in the right upper side of your abdomen, then the
gallbladder may be the problem, or the pancreas / stomach.
If it is in the right lower area of your abdomen, then the colon,
small intestine, ovaries (if still present). I see you have a history of
fecal impaction, so severe
constipation can also cause this. Another possibility is an early bowel obstruction, particularly with your history of multiple abdominal surgeries.
Abdominal pain should not be taken lightly, and i highly suggest you getting re-check. You will likely need a repeat imaging, either an
ultrasound or a repeat CT scan with contrast. Also bloodwork to check the liver, pancreas, white cells, red cells, urine tests.
If the pain seems to the physician like a
muscular pain, then muscle relaxants should have helped already.
Hope this helps, let me know if you have further questions or concerns
