A client who came to see me actually struggled to sit down on the couch due to sciatic pain within his back and legs.
After a couple of weeks he walked back in and I asked him how he's getting on. He told me that all was ok but that he was still having pain. I asked him how bad. He replied that it came on when he put his socks on. That was it. No other time.
I reminded him of his first visit to me and he was shocked. He had completely forgot just how bad the pain was. Yes he still has issues but he's improved tremendously.
It's only when we get reminded of how we were before do we appreciate just how far we have come.
