Sharp pain in upper back on left side?

I wasn't doing much activity today just cleaning and I noticed a pain in my back around my ribs on the left side. so I sat down and when I went to get up it felt like my back tightened up and I had shooting pain. It was so painful I couldn't move and had to lay down for a couple hours. I've been taking some advil but I'm still having pain when I twist or bend my back. any ideas?
