Hi I am a otherwise healthy 58 year old male but I have had pain for over a year below my belly button, on both sides. If I stand for over 30 min or try to walk a block I am in pain , turn white and want to vomit. I have had MRI and CT scan that has found no problems there. I have a large kidney stone that is to large to pass and has to be dealt with. Could the stone be causing the pain? Thank you
