When people get treatment for pain, sometimes they feel better just because they expect to feel better - not because the treatment actually changed anything in their body.

A transcutaneous electrical nerve stimulation device for the relief of neuropathic pain in NMOSD: A randomized, double-blind, sham-controlled trial
The study compared real TENS electrical nerve stimulation to fake TENS (sham) treatment. Both groups felt less pain afterward, but there was no real difference between them - meaning the improvement came from belief/treatment context, not from the actual electrical stimulation. This proves the placebo effect in pain management.
The Influence of Placebo Analgesia Manipulations on Pain Report, the Nociceptive Flexion Reflex, and Autonomic Responses to Pain.
The study found that people felt less pain when they expected pain relief (placebo), but the actual physical measure of pain processing in their spine showed the opposite - it was more active, not less. This means the feeling of pain relief came from psychological factors, not real physiological changes.
