Thanks, @choogirl. It looks like it's only temporary and it's now improving. It wasn't from yoga, I had it before the session and the yoga made it better temporarily but then it came back. I had a nice long epsom salt bath this evening and that was so relaxing. I shouldn't be such a wuss. Lots of people live with chronic pain and what I have is nothing compared to that. It was pretty bad for a few days but I now feel a bit silly for making a fuss, haha.
