I see a chiropractor or physio. Is this instead of that, or do they not interfere with each other?

They don't interfere with each other - quite the opposite. Quite a few of our clients came on the recommendation of a physiotherapist or chiropractor - some were told outright that gentle traction would do them good. We don't make diagnoses and we don't replace medical treatment; we're about gentle recovery and relief between visits and over the long run. If your specialist knows your condition, tell them about the hang and decompression, and keep doing what's already helping you.
