@bjgwellness I started MFR for thoracic outlet syndrome several years ago. It has helped a lot. My hands used to turn blue and get cold and that doesn't happen anymore. My scapulae (shoulder blades) are back into a more normal position on my back rather than in a forward position. During those years, I developed my spine disc problem and went through cervical spine surgery having a fusion. It took 2 years to find a surgeon who would help me and I was doing MFR that whole time which bought me some time before surgery and made the surgery go easier, but my progress with TOS had plateaued because the spine issue was causing neck spasms. After surgery, I had to wait until my spine began the fusion process before I could start up with MFR again which was at 3 months post op and I was working on the surgical scar tissue and tightness in my neck as well as strengthening because my neck was weak being in a neck brace for 3 months. My thoracic outlet syndrome had gotten worse because of the break after spine surgery. I have been doing MFR since surgery 5 years ago, but with a break from when the pandemic caused shutdowns in 2020. That is also when I broke my ankle, and had to do rehab for that instead after I started walking again so didn't do MFR on my neck for about a year. I restarted MFR at the beginning of this year to work on my neck and thoracic outlet syndrome. I'm going once a week now so the benefits will stretch through the calendar year. I also do self treating of stretches that I can do at home. MFR has helped me maintain better posture and body alignment. I also ride a horse which helps with core strength and that supports my spine so that complements what I do in physical therapy. I used to have a lot of arm pain which doesn't happen now unless there is something stressful or physical overexertion that can kick up symptoms by tightening everything. When you live with long term pain and muscle tightness, it changes and the therapist will work on different areas where ever it needs adjusting. Since your son is about 3 months post op now, he may want to ask his surgeon if he can do physical therapy. The surgical scar tissue can be treated with MFR and with having had 3 surgeries, it is probably something that needs work.
