I am 34 y.o unmarried female. I was recently diagnosed with endometriosis and chocolate cysts & underwent a bilateral laparoscopic cystectomy with adhesiolysis 2 weeks backs. Post op, i had urine retention issues & had to be on the catheter for 3 days. Urine issues are gone now. However, after a week of surgery, i am having pain in my lower back right side just above buttocks. Sometimes the pain is there on the sides of the hips. Taking painkillers mostly crocin advanced. I want to know the reason for such pain and whether it is normal. Currently on OVRAL L, augmentin 625, vibact, haem up and becozinc. Will this pain go away on its own? What should i do?
