My wife had back pain due to a disfigured vertebrae. That’s something they do not want to operate in until every other option is exhausted. Much of her pain and numbness is caused by imbalanced muscle development from a lifetime of incorrect posture and movements that compensated for the defective vertebrae. She’s worked with both a Physical Therapist and a Trainer to improve her strength and how she moves to the point that she is pain free 90% of the time. Both were referred to her by her doctors. They’re not part of a PT chain or gym.
