Between old football injuries, and being a cop for most of my adult life, I've had four surgerys on my right shoulder, one on my back, and the current Saw Bones wants to operate on my left should to relieve some spurs. Tore the rotor cuff in the right one two years ago.
My options were either find a comfortable bow or go to the crossbow. I started with the Mathews Legacy and now currently shoot the Mathews Outback. Big wheels, high let-off, smooth bows and moderate weight, (55#) allow me to still participate in Archery and Bowhunting. I do however, take a daily dose of pain medication that helps with the back injury and I assume helps with the shoulders too. Probably have to take it the rest of my life. This works for me. Maybe you or someone else reading your post can use this information.
