About 6 months ago I had my gull bladder removed due to severe pain. Now I am having extreme pain in my back and I can not keep anything in me, not even water. I have lost over 20 pounds in 2 weeks. I keep going to the ER, they rehydrate me and send me home. They have run every test possible and tell me that they cannot find anything wrong with me. i am in extreme pain and I am so weak due to the lack of nutrients and fluids. Please any ideas. Thank you and god bless.
