This is all IMO.
Drop the kinesiology. Go with the good ol' western med for now.
Bile acids aren't terribly high, but they do indicate that the liver is having a hard time functioning for whatever reason. I wouldn't say it's a shunt, but it's worth checking into. Spiking fevers is definitely a problem and it's been going on for two long. I don't think you would have to see an expert in liver issues right now, but to make sure you aren't wasting money, I'd go ahead and go to UT> Their diagnostics department is probably the highest you can go to in TN and then you won't have to end up going there after spending thousands at another specialist's office. Whatever it is (kinda does sound intestinal), UT should be able to handle it. Ask them to start slow (one test at a time if possible) to hopefully lessen the bill. If you go to another specialist and then have to go to UT later, they will likely insist on running all of the tests over again. So I'd go right to the top and get it over with.
