Yeah, that makes sense. My back was giving me some pretty bad spasms when I was passing the kidney stone. And it was really focused pain, right in the flank. Damn kidney stones...
I'll have to give those exercises a try. I should be able to get back on track fast, I used to be a ballet dancer, and had to keep good posture. :P
I wonder, would it also be caused by sleeping positions? I'm only ever comfortable sleeping on my stomach, which is bad, I know. Perhaps the way I stretch my back muscles when I sleep, or compress them, is keeping my shoulders so tight.
Wow, I didn't think shin splints were so muscle damage focused. I always figured I had chronic shin splints because I had osgood slaughter disease growing up, and never really gave my lower legs and knees the rest they needed.
The next time I get a massage, I'll see if she can massage the shins.
Thanks for all your advice, you've been very helpful.
