I had a colonoscopy one week ago. Since then, urination feels different..seems like a have to urinate alot and there is some stinging, cloudy, urine does not smell. I have had lower back ache along with this. The symptoms seem less each day, but the urine is yellow and very cloudy. Is this connected with the colonoscopy. I never have urinary tract infections, but had kidney disease at age 15. Age is 69 and female. Thank you.
