I don't know what to do. I have urinary retention real bad right now. I'm like crossing my legs because I have to go so badly but I then am straining so hard and I can't go. I've put on 3.2 pounds in water weight. I've been trying to go all night. I don't know if its my kidneys or what. Should I go to the ER in the morning or call my kidney doctor or just wait a bit or what.
