I am in a very critical condition. Medicine does not work. My problem is-whenever I hav sex with my wife, I feel a cramp in both left and right side of my belly. When cramped, whatever I eat remains undigested. Then I hav frequent urination and dry stool and burning sensation in anal. What is the reason of this cramp? How can I get rid of that? Should I stop having sex? If yes then how long? Please help me doctors I am on the verge of death.
