BPSDB There's a plethora of a letter at A Case of Chiropractic Manipulation Immediately Relieving Depression with Chronic Pain:
Patient A, a 41-year-old Taiwanese male, suffered from intermittent dysthymia which presented with minor low mood, insomnia, anxiety, chest tightness, back pain, and subjectively mild occupational difficulty... patient A received a single chiropractic spinal manipulation. The chiropractor noticed a minor deformity in the thoracic spine, and a traction technique was administered. He experienced immediate relief from back pain. The following day he reported complete relief of chest tightness, dysthymia, fatigue, and insomnia, with HAM-D, TDQ, and VAS scores of 0 for all.
“No, no, I'm fine now, no need to do any more chiropractic on me, I'll be off then...”
Reminds me slightly of various Blue Jam sketches. (Meanwhile, proper holistic back-pain suggestions.)
