i sit a lot at work, working on computer all day. I am not overweight, actually in very good health. I have noticed the last couple of months that my right buttock hurts and so i moved my chair around so that i wouldn t have pressure there, but it still hurts. This feels like a burning deep down inside. There is no skin tear and no redness as i can see (I am African American so hard to tell) Could this be a PU developing underneath the skin that will break thru oneday? I sure hope not. What can i do besides stand and use my computer. I have changed chairs, use cushions, etc. it still hurts, really bad.
