Tweeked my left shoulder (AGAIN) two weeks ago doing bench press with 45 lb dumbells. Kind of a bummer after being pain free for a year. Nothing bad but enough that I haven't lifted weights since. Was doing the reps quickly and can't point to an instant when I actually hurt it but woke up the next day with it low grade aching and it has ever since. Thinking its tendonitis or impingement. I largely credit hanging from a pull-up bar and weight lifting for resolving my prior shoulder issues and then over-did it just one time. Thankfully this is minor and hasn't effected surfing. Only thing it seems to effect is sleeping.
