Retention with exercise/exertion

Im not sure if this is related to IC but I’ve noticed I cannot pee when I’m exercising or being pretty active like hiking. It isn’t an issue of not hydrating, as it occurs regardless of how much water I drink. My bladder will feel full and painful but I can’t seem to empty it. When I’ve rested a while after excercise eventually I start to be able to pee normally again and I don’t really experience retention in any other context.

This particular issue has gotten a lot worse recently, and I read somewhere else that amitriptyline can cause retention which I recently started taking, so im going to schedule with my urologist to discuss but I’m wondering if anyone else has this symptom with exercise?
