My left side has been hurting all day. Mostly when I bend over or sit down. Its pretty low for the most part but this morning I could feel it all the way up to my rib cage. It may be ligament pain, I have read a few things about that. Is there anything I can do to make it hurt a little less. I am very active at my job and its affecting my work. I don't really want to take any medicine because I'm only 9+5. Stretches? Heat? Rest?
