The steroids injections work well for me, too. They have side effects but not as bad as taking oral steroids for prolonged periods. I don't care if I have to have steroid injections every few months. Better than not being able to get around and enjoy working in the garden. Chronic pain not only darkens your days but can be very isolating. It's hard to enjoy socialising when every move, and even sitting, hurts.
Good luck with the gut and getting some relief for the arthritis. And, no, I'm not ready to pull the plug either, but it's as comfort to know that it will be an option if needed down the track. Our legislation has only been in place for as year or so - we're bit slow down here in Tas.
