This is the new medical advice on the AAFP website to doctors written in 2003: enlarge figure 3.

Yes, do make a list of what you take and for how long.
But don't expect Mayo to care a whit about it... their website
is mostly anti-supplement, with a few exceptions.

I think your evaluation of the anatomical problem in your spine
would be the focus of their opinion.
