Thank you for posting about how you are navigating the shoals of a really difficult situation with, well, grace. The body-building background sounds as if it gives you extra insight into how best to help your body as well.

I had a serious back injury years back and the TENS unit was a great help. It didn't counteract the most severe pain, but it did help take my attention away from it. And helped me fall asleep, along with, for some reason, Baroque music. I could adjust the TENS unit to almost be in sync with the music by tweaking amplitude and periodicity of the TENS stimulation then lower the intensity. It sounds odd but having those three little controls was about the only control I had over pain, or pain awareness, so it was a blessing.
