Hello there,
I have two now grown kids who had rib resection surgery several years ago for TOS arm and neck pain issues. My daughters rib grew back entirely.
I also have had rib resection for TOS, all 3 of us have cervical ribs.
I have had excellent new physical therapy the past 6 months and have had much improvement in my pain levels. Look for a physical therapist who specialises in neck trauma/issues-they should be knowledgeable about TOS. ALso, anyone trained in the Butler/Moseley 'Explain Pain' or NOIgroup about how the brain affects pain cycles.
If I'd had good p.t. 5 years ago I likely would not have had surgery, and I suspect my kids may not have either.
