Day 5 is getting better, it's either the S2 nerve or a start of a Hernia. When I was doing my home therapy using a threadmill I would get minor groin pain on both sides. On a bad day I can feel my scar tissue around the L5-S1, it's the size of a coffee cup. These patches I use are great, numbs the area! My main problem is scar tissue wrapped around the S1 nerve, half of my right foot is dead. The smoother the floor the worst the pain would get, the only way I could walk pain free at work was to use 2 patchs on right foot. I did this for 2 years and I'm retired now from the UAW autoworkers, I'm 52 now and want to enjoy the good-life. Thanx's for the Support Woody
