Haven't posted on here in a while, but lately my left arm will start feeling sore, like the muscles are all achy and I haven't really done anything to make them sore at all, which is weird. Also, when I am putting on my makeup and other small things, it's like I notice my hand is kind of trembling sometimes. I've noticed it does that after I've had coffee, but also at other times too when I've had no caffeine to stimulate my system. I am left-handed so I do use that arm/hand more, obviously, but now I"m thinking I've got some kind of nerve damage or muscle disease and it's freaking me out. Like right now, my muscles feel achy , like I just did really hard workout, but the only major thing I did was vacuum and that certainly wasn't that strenuous. Really wish it would stop.
