How long can you have a pinched nerve or a herniated disc or suffer from nerve pain? And even with mild scoliosis can this affect your disc in your back and injuries that can happen to your the rustic spine

It varies. Pain arising from a "pinched" or irritated nerve in the spine usually goes away within a few weeks to a few months depending on the cause. However in a minority of cases the pain can persist for months or even years. Scoliosis is rotation/curvature of the spine most often in the middle back (thoracic) or lower back (lumbar). This can cause added stress to the discs in your spine.
