Hello, the.man.coolness, You say that you have had this condition for over a year now. Other than the severe abdominal pain, if you are also experiencing bouts of diarrhea or constipation, we can think of different conditions. But, I am concerned about the finding of inflammation, patchy in nature in your intestines, probably in your small bowel. Your colonoscopy was negative according to you. One condition that would show these types of changes is Crohn s Disease . This is more common between the ages of teens to the thirtty plus, although can occur at any age. Depending on the extent of small bowel involvement, the symptoms can vary. Diarrhea, weight loss due to malabsorption, vitamin and mineral deficiencies can be present. Anemia, joint pains, skin and eye problems also are associated with this. If you have a family history of Crohn s or ulcerative colitis, your risk is greater to have this. You did not mention any x-ray studies , like upper GI and small bowel x-rays (Not CT-Scan). How about all your blood tests ? Stool studies ? We need more information. If the pain is severe enough that you need strong pain killers, I think you need additional work up. Hope to hear from you with more information. Wish you well.
