Hello all I'm a fellow sufferer with chronic pain. I know I have tight muscles and muscle tension, which makes everything worse. There are some reasons why I might have pain but not to this extent. Although not, everyone is open to this however, if nothing else has worked. I would highly recommend delving into the mind body world, a.k.a. Neuroplastic syndromes
Most chronic pain is actually reversible and often not related to the structural abnormalities we all have. I believe strongly in this however for me, it's much more of an autonomic nervous system issue I believe and I'm have an atypical CRPS, which has made my pain increase. I would recommend going back to basics Reid John, Saryn,
Healing back pain.
Also ATNS association for the treatment of neuroplastic syndromes, symptomatic.me

No harm in looking up practitioners there are all the resources and there's plenty on YouTube
Dan Buglio, who was crooked from pain for 13 years has many videos on this
Dan Ratner pain psychologist also history of chronic pain he has cured
Howard Schubiner MD just wrote a new addition of his book unlearn your pain so there's lots to look at and it really can't hurt only the edge to potential healing
IMHO
