Thanks, couchtater.
The pain I get is weird becasue even though it's fairly painful when it happens, the worst of it fades fairly quickly, and even when I touch the spot when it's hurting, pressing on it doesn't make it hurt more. As a matter of fact, I usually can't "find" the pain by pressing on it...very odd!
Of course, being the anxiety-riddled person that I am, my mind goes straight to some worst-case scenario of bone cancer or something. It's been going on for a few weeks now, and though it's not really getting worse, it hasn't left either. Just another "mystery pain", I guess!
