pain
"works good if you use three of them at the same time.

Suffered Spinal injury in AFG. Multiple Surgeries did little to fix problem. I am happy that I am walking. Pain is usually severe enough that Only  the Colorado patch works. These are for when I'm not in Colorado.

Have to use 3 to get any results though. They could use a better adhesive. 100mph tape works best to hold them on."
