I have episodes of vomiting that has lasted about a year and a half now. I am 24 years old and I have been treated in the ER several times for dehydration because of vomiting. There is no specific pattern or trigger that I or my Doctors can pinpoint. I will wake up one morning and start throwing up stomach acid for 14 hours, not be able to keep water down and will be fine the next day. Sometimes I throw up after meals for no reason, all with different foods that have no common ingredient (fruit, pizza, salad, toast, yogurt) I also cannot drink alcohol at all anymore. I was never a heavy drinker but very fond of wine; I can't even drink a half glass without throwing up for hours or days, I opt not to drink anymore. When these episodes occur I get excruciating pain in the center of my upper abdomen; it feels like a tight squeezing feeling, I also get pain in my lower left and right abdomen that feels like cramping and sharp shooting pains. I will also get pain in my right should blade. During an episode I am so focused on the pain I can't process what people are telling me, I also have problems forming sentences and feel like I am completely out of it. Chills, profuse sweating, and a feeling of diarrhea with no bowel movement also accompany my episodes. Since December 2009 I have lost 20lbs because I am scared to eat in case it is food triggering it. All I eat is ensure, soup, crackers, applesauce, and yogurt. I have had ultrasounds done on my gallbladder and my ovaries both were normal. I tested negative for diabetes, all STDs, and H Pylori. I have been referred to have an endoscopy but with all of my visits to the ER for IV fluids and medicine the past year and all of the tests done thus far, I cannot afford to do this procedure right now. Is there any help you could provide in finding a diagnosis? I would really appreciate your time.
