This is the reply I got from Dr Braverman......
...We have had success with AS . But of course you need to be sure it is the AS that is the problem (but I do think that is most likely). I would need to get testing on you to see where we would need to focus the treatments. I would want to look at cellular and antibody profiles on you as well as a complete cytokine profile (serum and cellular). But I'm sure I can at least give you answers. At that point I would be able to recommend supplements as well.
If you would like my help please fill out the consult form on our website....
