I have bursitis in both hips plus a blown disc in the lower back so sitting or standing is a problem for me. I tend to sew for a short period, then get up and press, cut or whatever for a short period. Then go back to the sewing machine, etc. When I'm at the quilting machine, I do the same with alternating sitting and standing. Relieves some of the pressure but not all. I also have issues with both feet so standing for too long a period makes them hurt too. Its just not fair.........now that we're retired and have the time to spend doing what we love to do, our bodies fight us. As I tell my friends, my spirit is willing but my body can't keep up with the pace.
