I experienced sciatica several years ago when my L5/S1 disc herniated. It was very painful, but the pain went away completely after surgery.
Unfortunately for me, the same disc later ruptured and the pain was so bad, I was unable to walk. I had to have a second surgery to relieve the pressure on the sciatic nerve. Also unfortunately, the nerve damage is permanent now. I live with daily pain from sciatica.
I'm also prove to tendonitis and I have rotator cuff pain, tennis elbow, and DeQuervain's tendonitis/Carpal tunnel syndrome in both hands. I've had 5 surgeries to open up those nerve tunnels, but I still need one more surgery in my left thumb.
Nerve pain is the worst. There is very little relief from it. I've tried Tens units, ice, heat, hot tubs, acupuncture, massage, you name it. The older I get, the worse the pain gets. I'm only 62 now, but I wonder if I will make it to my goal death age of 84.
I won't make it pain free, that's for sure.
