Proper rehab is important. Most people who require shoulder surgery through "non accidents"/ "wear and tear" do so due to poor shoulder development in the rear delts.
I learned from my uncle who had surgery twice. In his first rehab they didn't focus on shoulder posture/position. They just went for strength recovery which undid the surgery. Once I got older and my shoulder started aching and making noises I started hitting the rear delts like it was priority 1. Now no pain (which was terrible after sleeping), no noises, surgery avoided.
Gave 4 people this advice. Three people followed it and were amazed how quickly it remedies things. One didn't try and they ended up going for surgery. Try it
Again this is normal wear down or rehab aid not injury fix.
