He gave me a chiropractic adjustment that caused extreme pain. Months later, my doctor thought it was a compressed disk. A bone scan and another X-ray showed nothing. Another doctor suggested a MRI, which detected a severely herniated disk. A herniated disc is one that has been compressed and pushes out, pressing against the nerve leaving the spinal cord, often down the arms or legs.
Most people believe that the first doctor's treatment is most appropriate.
Nothing more is needed for a successful recovery. If symptoms persist, additional treatment may be needed. Without seeing you in February or March, it is impossible to say what should have happened, but it is clear that your first doctor was acting within the standard of care and was not negligent. Often a second opinion is more aggressive than the first. For this reason, it is not surprising that the MRI was obtained once you saw the second doctor.
