Kris,
You are absolutely correct and good for you for being open minded enough to try a few different things! As you mentioned, most of these are noninvasive and are relatively easy to experiment with.
It's so very, very hard to put numbers on pain but I will venture to say that I've decreased my pain (or possibly my "perception" of pain", but hey perception is reality when it comes to pain) by 30% or more with the complementary therapies that I have introduced into my daily routine.
Go slow and have patience. Good luck and be sure to keep us updated!!
