i can hardly believe how this works on soft tissue pain of the joints. i have severe pain diseases including crps, spinal cord injury, neuroma on my neck and trigeminal neuralgia migranes when my neck goes out of position. if i ever have other pains they are off the charts. one severe flair was level 10 pain and i felt like i was going to lose my mind with the pain and i remembered i bought this thing. i grabbed it thinking it wouldn't possibly work and i focused it on my thoracic spine where i have retrolethesis. Holy mackeral. it took the pain down like some bizarre magic from a 10 to a 7 in about 4 seconds. wth?! how is that even possible? i started researching photobiomodulation since then and now i get how it works on a micro level. I went and bought a whole body infrared red light therapy as well. I want to heal my body and i highly recommend this. I even told my pain management doctor about it. He was very skeptical until i kept telling how it worked and sent him studies.
