You know, this is a great subject because many shooters (including me) are and have been adversely affected by surgery.
Mine was anterior lumbar surgery that the final result had made my situation worse. Now i can no longer shoot a compound bow, and have a hard time shooting rifles while standing as well. In essence, i lost a severe competitive edge because i used to shoot in a bow league and various rifle/shotgun sports, which i don't have the ability to do now....unless i'm shooting while on pain meds, and like that's ever going to happen because i don't shoot high!
The thing in my case, i had a doctor say that i'd be fine to shoot again..... Well, it's been about three years since and i use my lower body (lumbar) as a pivot point as least as possible. Although (and thank God) pistol/revolver and precision rifle shooting has been a great strong point of mine, i can shoot rifles in a sitting or modified prone position, and i'm trying triditional archery now which 'so far' i'm having minimal problems shooting a recurve (which it seems my recurve is 3 times lighter than what my fully dressed compound was).
But i will admit this, the pain i deal with now has given me the ability to not 'jump the trigger' so to speak, and has calmed my nerves quite a bit.
How many others have been affected by any other surgeries?
