When fine needles are placed at specific anatomical points, they stimulate peripheral sensory nerves. This triggers a cascade of responses — locally in the tissue, at the spinal cord level, and in the brain — that include:
- Release of endorphins and enkephalins — the body's natural pain-killers
- Modulation of pain signals at the spinal cord (gate control)
- Muscle relaxation — reducing spasm and trigger point pain
- Improved local circulation and tissue oxygenation
- Central effects that reduce the amplification of chronic pain signals
- Immune modulation — influencing local and systemic immune responses
This is why western veterinary acupuncture is particularly effective for chronic pain conditions, musculoskeletal problems and certain neurological presentations — the very conditions where conventional pharmaceutical management alone often reaches its limits.
