You know, with back pain and leg pain and foot pain and headaches, it really sounds to me like a chiropractor and/or an acupuncturist might be a good avenue to explore. This whole collection taken together seem like spinal alignment or nerve issues that you might be able to take care of without all the worrisome medication. Just a thought. I know your insurance doesn't likely cover those (we're on Tricare, retired military as well), so that could be a problem, but if you can swing it, it's worth a try.
