Mild pain after Bilateral DJ stenting.

About a month back I had a right URSL done for a 8mm ureteric stone with bilateral dj stenting. I had plans of getting a RIRS done for a left renal stone of size 10mm but couldn't do it because of my mom's health problems. I had severe infections after DJ stent placement that I had to put on Ceftazidime + Tazobactum injections for 3 days. DJ stents were removed 10 days after surgery. So now despite 15 days after DJ stent removal my left kidney side there is still mild squeezing pain along with light stabbing pain that happens near the ribcage area. Is it normal? Is it because of the stone? Prior to surgery I had no such pain. The doctor who performed my surgery is on leave currently so I'm unable to ask him. No fever, urine is clear but I get occasional chills. Also from the past 2-3 days I've noticed my stool green with visible green ink like color.
