I had reconstruction of the shoulder in 2002. I have some artificial parts and some repairs. Most of this came from being a left-handed hockey player and doing a lot of heavy checking with my right shoulder. After surgery the Doc said no shooting in his words "bigger than a 22". That was to last 5-6 months. Well with bird season in just one month I didn't want to miss it and thought I'd be fine with a 28 gauge. I made it through the day and a few shots didn't seem to have effect so I slacked off on PT after that too. Well, it never did heal right. If I shoot any long-gun just a few shots I have a severely discolored shoulder even now, 18 years later. If I shoot a lot of heavy recoiling shots I will develop swelling and a pain that runs from shoulder up into my neck and causes a bad headache. Doc says I should have another surgery to fix this, but no thanks. I don't shoot much with light, heavy recoiling guns with narrow butts. Something 8 or more pounds with a wide, large and flat butt will make me colorful but not sore if I keep the shot count down. I can easily survive a day of dove shooting with 50 or so shots out of a 20 gauge percussion shotgun, but not several days in a row like that. A day at the range with 25 or less shots is not problem - colorful but not painful. I like .54 and .62 caliber percussion and flintlock and use 19, 20 and 20 gauge percussion shotguns. My advice is to take off of shooting and other strains for the prescribed period and complete all PT and follow-up visits. After that, get back into it slowly and incrementally. Do not exceed your threshold for discomfort. I think if your shoulder is done right you will be relieved and surprised at how comfortable shooting will be again.
