@irol, @artscaping : Re. pigeon pose —— will try, but the bent inward motion of the knee is the one that still hurts quite a bit. I do a series of easier exercises that my PT suggested 5 years ago to control Sciatica. He basically called it “flossing the sciatic nerve and stretching the piriformis area”. I may not be as flexible as Chris in general, but my TKR PT was floored how great my range of motion of the hip flexors is.
To irol: I have had Sciatica on and off for roughly 10 years. 6 years ago it was bad enough for me to succumb to spinal injections, twice within the span of 9 months. However, since I started doing the daily exercises, I was able to keep it in check. It definitely did flare up again after TKR, but that probably has to do with uneven gait. Now it’s pretty much gone, unless I have to do a lot of sitting (2 4 1/2 hour flights, and 2 3 1/2 hours train rides in the last 10 days.....)
