My experience with Kidney stone!!!

Hey all, I had severe back pain and vomiting + nausea a week ago, so I initially ignored thinking it must be pre period cramps or something, but after a CT Scan, I figured out there was a stone (6.4mm), surprisingly trying to come out and not get stuck there inside, so the urologist told me to take some tablets and monitor for a few days an let the stone come out itself, but we gave 3 days and it didn’t work so, he suggested I get the surgery and put the stent.

Got the surgery yesterday, completely painless and was done under general anaesthesia. I only remember going in and coming out of OT, now the stent part, i do have pain and discomfort, doctor said they will remove it under local anaesthesia after 3 weeks from now which is on 19th and I have my sem end exams, can someone please help me out with the pain management???
