@wandamiller @vklittle61 Remember, we are not doctors and diagnosticians. So the suggestions I had for others were my story and suggestions- not a diagnosis. However, they may be relevant. Piriformis syndrome (which I had, among other things), is a form of sciatica in that the piriformis muscle can compress the sciatic nerve. Stretching and exercise are known to help this. I also did used to have burning sensations in my lower legs - a characteristic of sciatica. Doctors generally use the dermatome concept (lower leg issues map to S1 (sacral) nerve segment. In fact, it is possible that (trigger points near the piriformis) could be causing my sitting pain as well as in some others who have sitting pain. However, I have lower lumbar DDD with bulging disks (and some foraminal stenosis), torn hip labral cartilage (both hips), hip impingement (large cams). You take your pick. However, my symptoms went way beyond merely sciatica (my pain level was not too bad during most of this, too- but it was always there). It's a wonder I'm not in more pain. I can stand and walk a lot with no pain. For me motion helps me feel better.

My pain doctor explained that many pains below the spinal nerves actually come from pinches / compression in spinal nerves up above. It can be very complex to get to the root causes. A lot of my pain was myofascial. I personally think I've had some tension in nerve plexuses - such as the psoas (where the lumbar plexus passes thru). These nerves later goes onto form the lumbosacral plexus. This causes digestive issues, too. Stretching, exercise and very deep breathing have really helped relax a lot of that tension. Most doctors don't know anything about any of that or how to treat it. Some physical therapists know various helpful things. All that being said, things have gotten a lot better.
