No shoulder pain experienced that didn't go away soon after finishing a swim. I was told that if the shoulder didn't hurt ... then I wasn't doing it correctly. Makes sense to anyone?
I did trip over skate toe pick and landing on the left shoulder really messed it up. It became frozen -- did the chiropractor visit thing for a while ... very little improvement. A couple of years later I lost a ski while going over a jump and landed on the same shoulder ..... instant recovery !!! Swimming hasn't had any effect on that shoulder. But the next time I hurt one I may be foolish enough to try a ski jump with just one ski !!!
If you're not swimming; then you should be skiing......
