Exercising the core is always good.
Nerve damage obviously is never good. Threw my back out at work and started getting a "dumb" rightt leg. I was tripping over nothing. Did almost 6 months of therapy since the bulge was there but just starting to penetrate the spinal cord. Nothing but core and no issues since.
Normal back pain I guess for a 50 year old who builds 700 lb transmissions everyday would get I guess but no nerve issues
