Intense pain while urinating

Hey everyone! It's my 8th day with a JJ stent on my right kidney. Got a 9mm stone removed. I feel awesome, I can barely feel the stent, so I've been able to go back to school this week like usual. The only problem is that since Sunday I've been feeling intense pressure and pain on my kidney when I pee. Only when I pee. I don't feel said pain anywhere else but the kidney. Has anyone had this happen before? It's not unbearable, I can deal with it, but I've been dreading going to the bathroom. I'm drinking about 2.5 liters of water daily. Should I contact my urologist?
