I have had 5 back surgeries and I do NOT do all my rotary cutting at once. I may cut enough for portions of my next quilt in between sewing and pressing for the once I am working on. If you do the same motion-whatever it is-in excess, you will feel it. Besides a good height (stomach) make sure your cutting mat is "big"' enough and you are not leaning forward too far when you cut. With proper folding before cutting, you should be standing pretty "straight up" for the entire cut with minimal leaning. By working in the cutting with other quilt activities you should lessen the need for any medication. Good luck!
