I had it down my left rear for years, I later ended up with a pinched nerve and after an MRI I was told I had spinal stenosis and they wanted to fuse 2 lower levels of my spine, spine doc said it was pretty bad. At the time I was in so much pain, on all sorts of opiods and they did not help. I decided to go to a back center where they did chiropractics, massage, decompression. After about a month, I was able to walk again and my sciatica has never come back. I still have a spine that looks like a question mark but I am not in the severe pain anymore. I swear it was the decompression table that stretched me out.
