body, why do you hate me?

[derien]

For no apparent reason the muscles that hold down my left shoulder blade have decided to be tweaky, today. It's really slow getting anything done where I have to take several deep breaths and try to fight against the pain, and sometimes curse a little, whenever I have to use my arms or lean over. All I can think is that it's from being in such a cold house and not doing much for the past week. I did try to lift weights a little, two days ago, but everything has seemed completely fine until this morning. Well, yesterday my lower back tweaked, but not as painfully.
