@dickiedo @scgraham My physical therapist told me it's common to have tight illiotibial bands in your legs and I can imagine that after knee surgery, that may get even tighter. All surgeries create scar tissue in the fascia and because fascia is a body wide web of interconnected tissue, it gets tighter. That also happens when you stop moving and you loose your flexibility. Then we sit too much and our hips get tight because of not standing and walking around, and all of that pulls on your lumbar spine. The psoas muscles connect from the spine to the pelvis and get tight. That does happen to me, and my physical therapist works on them. All of this body tightness can cause nerve compression because nerves pass through some very small spaces and between bones and ligaments. I have not had knee surgery, but I have had spine surgery and I need to stretch out the incision area when it gets tight. I have been doing myofascial release for several years before and after spine surgery and it helps me a lot. It is something to try, and you need to be patient while you work through layers that took years to form. @ scgraham I think MFR can help you. I have been able to recover from my surgery without pain drugs, and having done MFR extensively before surgery helped me recover better. I was doing MFR for thoracic outlet syndrome which is a compression of nerves and blood vessels under the collar bone which is close to the area of my surgery. There are also some syndromes that happen when the pelvis is out of alignment that cause sciatic pain. Here is a link. https://trainingandrehabilitation.com/identify-treat-lumbar-plexus-compression-syndrome-lpcs/ This link shows the muscles of the hips and pelvis and how it attaches to the legs. https://trainingandrehabilitation.com/causes-hip-pain-how-to-fix/ This link shows physical therapy techniques, and you should get clearance from your doctor or physical therapist as to what is right for you. MFR is gentle and similar to stretches done in Yoga by holding a stretch and waiting for the fascia to start to slide. Some doctors don't recognize the benefits of MFR work, but many do recommend it.
