I feel your pain Rosco, it always makes me cringe when I think of someone going under the knife and I certainly wish Jerry a speedy recovery.
I also carry internal hardware courtesy of a Speedway bike and was offered a Shoulder Fusion about 10 years ago, but as that would mean the end of doing anything even slightly exciting, inc - earning a crust in my trade, I've put it off.
Living with chronic pain does get tough and the day will definitely come when I have no choice, but not just yet.
I've got a comeback to make. Silly old fart.
