I messed up my arm on Saturday, and working on Sunday just made it worse. When I woke up Monday morning, it hurt from my neck to my elbow, and down my back some. I took a muscle relaxer and went to bed, but when I woke up I was pretty ill and had to rush to the bathroom. Spent the rest of the day throwing up. At first I thought it was the muscle relaxer, but it went on far longer than it should have. I finally stopped at about 3:30 in the morning and got some sleep. I feel better today - the headache is mostly gone and my stomach is no longer queasy (though it feels tender).
What a day.
