Hi Don,
You might try 100 mg.
R-Lipoic Acid and 500 mg.
Pantothenic Acid (vitamin B5) every morning for the burning pain; it virtually eliminated mine.
I have some other chronic pain issues that further complicate exercise, but I walk when I can, and have begun doing either a Tai Chi or gentle stretching routine (depending on... things) as many times a week as I can stand.
Everything (exercise) you're doing sounds great as long as you don't experience any deleterious repercussions.
