Hypnotherapy for chronic pain: a skeptic's take

I was ready to dismiss this one

Chronic pain is the category where alternative treatments tend to over-promise and under-deliver. We came into the pain literature expecting the same from hypnosis. We were wrong, and we're still not sure how wrong, which is an unusual place to land for a team used to being a hard sell.

The short version: for a subset of chronic pain conditions (fibromyalgia, tension headache, some forms of back pain) hypnotherapy produces effect sizes in the same ballpark as first-line pharmacotherapy, with fewer side effects and durable benefit past the treatment window. For acute pain (dental, post-op, burn care) the evidence is even stronger.

A 2019 meta-analysis in Neuroscience and Biobehavioral Reviews pulled 85 controlled trials and found moderate to large effect sizes for hypnotic analgesia, with the largest effects in highly suggestible people. That last part is the caveat. Hypnotherapy works better for some people than others, and about 10-15% of the population are very high responders.

Why it probably works

Pain isn't just a signal from the tissue. It's a perceptual construction your brain builds out of sensory input, expectation, emotion, and context. That's why a paper cut hurts more when you're already stressed and less when you're distracted. Hypnosis works on the construction layer, not the tissue layer.

Does that mean the pain was never real? Absolutely not. The construction layer is where pain actually happens. Hypnosis changes the construction, and therefore changes the pain. It's not pretending to feel better, it's literally feeling better.
