Understand, these treatments are low (not zero) risk, but for what purpose? Contained herniation means that there is no pressure on the nerves, and the disc is simply not in a "normal" location within the disc space.
Study? Fine. These haven't worked except temporarily in the lumbar spine. I would be pessimistic. Maximize mckenzie pt. Not heat/us/tens
as they are useless. If no other option, fine.
