A client being treated (successfully) for knee pain asked how the laser alleviated pain immediately. While there has been extensive research to show that the laser works to relieve pain, there are no definitive answers as to how. What is known is that cold laser therapy increases the release of endorphins, blocks firing of pain fibers, increases nitric oxide production, increases the levels of acetylcholine (which regenerates damaged nerves), and decreases levels of inflammatory chemicals.
Horses and dogs can't tell me that their pain is gone, but when I see them licking their lips and closing their eyes so peacefully, I get the message!
