I had much much worse symptoms than you that would come and go for 10 years before I got my first scope at age 31. I was diagnosed with Ulcerative Colitis. Had another scope 2 years later, I had changed my diet and did all natural treatments, colitis gone! Anywho, at your age CC would be practically unheard of, there are a lot of other things that could cause your symptoms. Best of luck, you're almost there! The drugs are GREAT and you'll have a diagnosis by the time you wake up. Update us please.
