Heya, Shane!
If I hold the arm straight and make a tense fist positioned as if I am holding a coffee cup, the ache is along the top (mostly) and outside (a little) of the arm just below the elbow. The pain feels deep like the bone is aching, and radiates along the arm from that point. I’m not sure, but I *think* outside elbow injuries are “tennis” elbow?
Anyway, I’ve looked at other things I do: I have some anti-ergonomic stuff going on at my desk at home. Because of how my keyboard tray sits, the mouse isn’t at the same level as the keyboard: I don’t think that helps. So I’ve been playing with various ways to bring it in line. I’ve noticed that the pain is a bit less significant and frequent than it was a couple of weeks ago. I notice it most frequently if I “reach” for something and pick it up, even something as small as a cup of coffee or something. I’ve been taking “joint support” vitamins (glucosamine, chondroitin, and some other stuff) for several months, since before the problem started. But I’m not sure I’m doing all the right things yet. I think I first noticed the pain back in July, so that’s over two months now.
Exercise seems counter-intuitive to me: how do I know if the exercise isn’t putting more strain on the already damaged tendon? I’m prone to just babying the arm: it’s not like there is much muscle there to begin with 😉
