I found out about a month ago that I have crohns disease. I ended up n the er for back pain they did some tests did an ultrasound and a ct of my abdomen looking for kidney stones and told me I had crohns. I go next week for more tests to confirm the diagnoses. I don't know if its the stress or what but I have been very sick this past week. Throwing up and all that good stuff. I have ran no fever with this so im just wondering if this is part of the disease or am I stressing myself out and causing myself to be sick? I dont know anything about crohns. My father has ulcerative colitis are they similar to each other?
