This is a biggie in things to be thankful for. There have been periods in my life when I had a lot of pain from my bad hip joints and sciatica. However, because of the blessings of modern medicine, I've had both hip joints replaced and I can get occasional epidural steroid injections to relieve the sciatica.
Since I retired, I no longer get stress headaches. I used to come home from work and take a nap to get through the rest of the day. I now sleep as late as I want (barring hungry kitties waking me for breakfast) and I stay up as late as I want. I can get out to go places and do things and I love it.
My heart goes out to all those with chronic pain. I know how pain colors everything in your life and takes away the joy. It takes away your purpose and feelings of self-worth, and it even haunts you for a long time after it has gone.
So, I am enjoying this pain-free period of my life while it lasts, because nothing lasts forever.
