I cant sit for very long - about 10-15 min and my hands turn red and begin to swell. It's the pressure on my back, even a soft chair - just the pressure on my shoulderblades hurts right thru to my collar bones. I sit on the edge of my desk-chair, not leaning on anything. I used to lean back on a pillow, but even that is bothersome by th time my 20min limit is up for computer typing.
