@artscaping @ssbionicknee Thanks for asking me to join your discussion. Both Chris and I know how much myofascial release has helped us with our own medical issues. All surgeries create scar tissue in the fascia which causes restrictions to normal movement, and over time, it all acts to glue muscle together and form knots and trigger points. All of that impacts muscle function, and as it tightens, muscles effectively get shorter and less able to move. Healthy fascia is a net that contains all the body organs and it even conducts electricity, and it exerts many pounds of force on the body. When your movement is impaired, it will start impairing other parts if the body and just gets worse unless you do something to stretch out the fascia and break scar tissue. There will be scar tissue from a surgical repair that is essential with tendon surgery, but also because of the surgical path, and that can cause restricted movement.

I have had a frozen shoulder, and a SLAP tear in my shoulder capsule, and thoracic outlet syndrome that makes my neck and shoulder muscles too tight and I am in physical therapy working on that with MFR and I have made great progress. When you have an injury, your body is trying to stabilize that to protect itself. I also had an old whiplash injury that caused muscle spasms that have been there for years with hard knots in my neck, and I had spine surgery 3 years ago and have been improving ever since because of MFR and physical therapy. Tight fascia causes pain, and sometimes also working on it in PT. My neck does get tight around my spine surgery incision, and I often stretch that area out. I would recommend asking your specialist if you can do MFR work with your restrictions. Here is the link to our Connect discussion on MFR, and you can find a provider search on the MFR website.
