I am very sorry that pain is a constant battle. I think ET is one of those things that is manageable on its own, but that complicates other things. I have severe scoliosis along with the bad mitral valve (there's a corrollation, I guess), and yoga helped with back pain. But, honestly, I had to start with just lying in bed in neutral spine position doing deep breathing at first. Can do more now. Took care of the sciatica and pinched nerves. But I still am very bent when walking without a cane, and can't go distances.
