Thanks Whitecell and Tacitus,
I am currently seeing a Chiro that is a bit alternative (promised a friend I would see her). She thinks I have some gut issues causing me to be acidic and preventing magnesium absoprtion. She has me on a diet which is like a LSD (not much fruit and only less sweet fruit. No wheat based products, minimal dairy, most vegies OK but no potatoes. No sugar. Lots of white meat). I have been on that for a few weeks. Some digestive related issues are a little improved, but they were minor really. My joint pain does not seem any better. One side effect of this is that I am having trouble maintaining weight as it is pretty low carb (I lost a few kg in the first week, and I am pretty skinny to start with). I am pretty under weight at the moment, and I want to try a fast, but may need to fatten up a little first.
With the antibiotic suggestion. This is something I want to try but I don't know how to. It is hard to find doctors in Australia that will allow me to try something that is not accepted protocol. If I can find some way to convince a doctor I have a condition that needs such an antibiotic treatment I may be able to do it. Any suggestions on that? What antibiotics do I want to use and what conditions do they normally treat?
