I’ve had back problems for the last decade. Sometimes I would wake up to horrible muscle spasms in my upper back. Doctors initially tried to addressed this with anti-inflammatories & muscle relaxers. They barely masked the symptoms and did nothing to address the root cause.
Moderate scoliosis (curvature of the spine) was suspected as the source of the problem. Physical therapy offered some relief, but the problems always seemed to come back a few months later.
