Have you tried a big pillow or wedge underneath knees? That has helped me a lot.
Yes. Has not helped the areas of pain - thigh calf heel or butt. Have ordered a cushion designed for sciatica relief, but it hasn’t been delivered yet.
That’s why I can’t sit at the computer. Tried all of my cushions pillows and chairs. The recliner is it and that’s only with the help of pillows and heating pad -especially the heat.
