Thanks for the query.
As your CT abdomen and pelvis is normal, there may not be any major problem.
You didn't mention any thing about your bowel habits, if you are having any constipation
etc., take laxatives which can relieve the symptoms to some extent.
You can go for culture and sensitivity of the urine, to find out any residual infection and take treatment accordingly.
Take analgesics and anti-inflammatory drugs prescribed by your doctor that can give some relief.
