Conclusion

Based on the symptom lists, it is clear that I have a higher amount of symptoms of Blau syndrome, but IBD seems to be a close second as well. Just symptoms aside, when reading about how the diseases present they all sound like they have features that I experience and and autoimmune disease seems likely. I don't feel comfortable specifying which one I definitely have, but would agree it is likely one of them and need to pursue this further.
