Bunny...Just want to offer my emotional support as you endure the stress of trying to exist in pain. I understand. We all do. I wish I had answers for you, but your questions are out of my league.
I grind through a life of pain also, with a demanding career. It's all I've ever known, but getting harder since I hit the "mid-century" mark. I certainly hope you can find the methods and modalities to enable you to continue your work. Meds help, but I'd be SOL if that's the only way I could endure. My PM trials aren't working out due to GI issues...hard choices?
