Hey 618huffman!
This thread is really old, but the information in it is still relevant.
In the 4 years since my last reply, I have been diagnosed with Behcets Disease, an autoimmune disease of the blood vessels. Behcets can mimic IBD as there are blood vessels in the entire body, including the intestines. I was diagnosed December of 2012.
As for the throbbing abdominal pain right below my left rib, I still have the same exact pain in the same exact place. It is still one of the central symptoms that I use as a way to figure out whats going on. I just actually got home from a pain management appointment, and I am on the butrans patch and tramadol to manage the pain so that I am able to lead somewhat of a normal life. They never found a reason for my pain. I have had many CT scans, colonoscopies (last in May), blood tests, etc. Earlier this year, when my rheumy figured out that I still had this chronic pain and was still on patch medication for it, he decided he is not being aggressive enough in my treatment. He thinks the pain might be current inflammation that needs to be treated. My pain management completely disagrees and thinks it is nerve damage where a major artery and collection of nerves intersect. The plan right now is to start Humira this Friday, and see if it changes my pain.
Kelly (SunshineSmile) is right, it could be endometriosis, depending on her age. It is a bit high for those fibers to appear, but it is possible. Endometriosis is diagnosed via exploratory surgery usually. I had heard I might have endo so many times, but then they decide not to do the surgery.
I have honestly gotten comfortable with not knowing why I'm in pain. My doctors believe me and keep me going. However, I truly hope your daughter's pain is not chronic.
Best of luck on your journey to figuring this out!
