We have some non-specific low back pain here, right around the bilateral sacroiliac joints. And I did 1000-3000 Hz for 5 minutes using the LaserStim over the area. I felt immediately sharp little needle-like pinpoints once the area was found with the laser and now the pain before I sat down is gone. That you’ve had for how many months? That I’ve had for six months. My own set of physicians could not relieve the pain. Nobody that I know has this machine, maybe if they had it would have been fixed months ago, but right now all I have is some slight tenderness, a little tightness in the hip flexor region, but sacrum T3 T4 is virtually pain-free. I absolutely would recommend this to physicians or even anybody who is just seeking relief, to find a physician who has one of the machines.
