I know from personal experience about the spine degeneration, spurs, and vertebral arthritis. She has GOT to stay off the grains, which are exacerbating the issue hugely. When I'm on grains, I can barely even tie my own shoes. Without them, I can do anything my trainer asks of me without pain or stiffness. That's how big of a different it makes.
Kidney stones: She is not drinking enough water and is taking in too much dairy. Use lemon to break up the stones that exist, then she can drink cranberry juice (unsweetened) with water in a 1:8 ratio (8 ounces of cranberry juice to 64 ounces of water) to keep the stones away. (Once you have them, there is a high likelihood of recurrence.) [This also is extremely effective for cellulite, BTW, but I'm sure that's low on her priority list at this point.]
See a naturopath for the thyroid issues.
I agree about the candidiasis, as above.
