I have a lot of abdominal pain one side,up near the ribs and lower down in the pelvic region?

I have a lot of abdominal pain one side,up near the ribs and lower down in the pelvic region,especially when I pass urine,this is very painful.
I had a operation to repair a prolapse 5 weeks ago.
I had a catheter in for 5 days after
After it was taken out I had a water infection,I was given some antibiotics,they didn’t work,so they prescribed some others as there were high white blood cells in the urine.before the abiotic were finished I went back to the doctors as I still did not feel right,there were still high white blood cells in the urine.bloods were done,nothing was found.i was still in pain so contacted them again,still had high white blood cells in urine,but still wasn’t given anything,bloods were repeated again,but said no sign of infection,although I was still in pain when urinating. I am now getting throbbing pain the other side of my abdomen,just under my ribs and getting pain on the backs of my legs
