Yes I had similar problems when I was 14 years old and at 15 years old I was diagnosed with inflammation causing severe pain and they were going to remove part of my intestines. Now I am 72 years old. A doctor in Italy saved my life with shots of Methionine, Vitamin B-12, and vitamin K. A two week treatment and I was brand new for 3 years. He basically cleaned my liver. No doctor in USA believes Crohn's can be liver related disorder. Dr Crohn's stated that the disease impacts the liver but he didn't conclude saying that a clean liver controls the disease. I put My Crohn's in remission by taking Liver Support Factors pills manufactured by Country Life and a diet of vegetables with chicken, fish, or meat. I removed breads, flour products, sugars, and carbohydrates from my diet. This doesn't mean that will help your son but be aware that Crohn's starts at 14 years old typically. Every time I eat carbohydrates I get pain now but vegetables is saving my health. I am learning that the liver loves vegetables specially raw and once fed that it removes inflammation. The pills actually is helping if I eat the wrong things otherwise I don't need any medication. One doctor only advised me of eating everything fresh and no processed foods or any soft drinks. Non of my GI doctors advised me correctly. I attend CCFA meetings and they bring a lot of GI doctors and nutritionist explaining how to control the specific problems. CCFA.org a lot of information is available. Also Webmd have some information. DrBerg.com have a lot of nutrition inf.
