Life-changing. As a nurse I've tried almost everything under the sun to treat my neck/shoulder/back injuries from car accidents. Within a month of NSA treatments from Dr. Mark the widespread pain became more localized. My adhesions/scar tissue were so resistant he tried Shockwave therapy, and after just the first treatment I could breathe easily and turn my head side to side. 2nd treatment allowed me to hike with a backpack. 3rd treatment and I'm almost PAIN FREE after years of stabbing pain.
