Thanks for posting your query here.
With the symptoms you have mentioned, it is quite possible that you have an infection. CT Scan
abdomen will help to give much clearer idea. Abdominal pain
you are experiencing seems to be colic
,coming from small bowel.
Have you got any vomiting
Have you tried any medications for pain?
Is the wound alright from hysterectomy?
I would suggest to get checked over in ER.
