Back pain is one of the most common reasons people go to their health care provider or miss work, and it is a leading cause of disability worldwide. Most back pain gradually improves with home treatment and over-the-counter pain relievers. But for some people, back pain can be a debilitating problem that requires more advanced treatment. One option for persistent back pain is an implanted spinal cord stimulator that uses low levels of electricity to intercept or block pain signals.

On the Mayo Clinic Q&A podcast, Dr. Tim Lamer, an anesthesiologist and pain medicine specialist at Mayo Clinic, explains how spinal cord stimulation devices are implanted and used to relieve persistent back pain.
