Thankfully, I don’t get much in the way of arm pain anymore. My shoulders used to hurt quite badly when I was younger because of the way I stood, my my surgery a few years ago seemed to solve that problem nicely.
That said, over the weekend, I got quite a bad bout of shoulder pain that I think started in my back and went down into my right arm. This may not sound like much, but I was surprised at just how much bother it caused me.
