I had to have my spleen and gallbladder removed in early 2008...my spleen was very enlarged, so I had a 10-inch incision down my abdomen. I was extremely sore and my doctor strictly limited what I could do. I had just bought a brand new sewing/embroidery machine, so I did sit down with it for very short periods of time. I agree that an adjustable office chair is very helpful. I also spent a lot of time with handcrafts and my laptop. :-)
