Seeking stellar myofascia or neuromuscular therapist

Chronic pain in back necessitating no sitting for longer than 15 minutes, no walking for more than 1/4 mile.  general back pain, occasional leg pain, and foot numbess.  Already tried lots of stretching, PT, epidural, MRIs, etc.  Seeking a doctor who can look at the bigger picture - is there a systemic postural problem that 4 decades has finally caught up?  is there a tendon that's snapped and MRI missed?  weekend athlete skiing, hiking, biking is now captive and mentally/emotionally challenged by pain and discomfort sapping all joy.

Please recommend a thoughtful, thorough, out of the box therapist or doctor who is willing to investigate causes, not just mask pain.  Prefer peninsula and south bay but will take your talented provider wherever.
