What kind of PT are you doing? Stretches, nerve glides, ultrasound, posturework, short reps of movements on one or both sides of body? Or are you working on strengthing, i.e; movements with weights, ball throwing, pull-down weights, etc? What is your nerve pain level like? All calmed down, no tingling, numbness or sharp pain, just dull muscle pain?

Are you off all meds rx'd by your surgeon for post-op? What is your activity level other than PT and craniosacral? How active are you during the day? Evening? Are you sleeping?

I found ultrasound to be really effective for muscle spasms at the surgical site post-op, you may want to ask about that if the PT hasn't already tried it. And be sure you aren't overdoing things, using the arm too much or attempting to push the recovery too fast - slow and easy does it or you WILL hear about it! Seems to be the top Drs consensus that it takes a full yer, maybe longer, to fully recover from TOS surgery - so you're still really early in the process. Patience is hard I know, BUT you've come so far, taking things slow a few more months is doable, right?

Best of wishes,
