I did, after my last scope. I was a little concerned because I had quite a large amount of bleeding after the scope and thought something was wrong, but when I called my doctor's office they told me not to worry about
it. The back pain went on for a day or two and then eventually went away. I just remember going in to work the next day after the scope and had trouble walking up the stairs because my back bothered me so much.
No idea what the problem was, but it did stop so hopefully yours will soon as well. Feel better!
