I finished swim around key west a few months ago but I'm still having this odd, sharp pain in my left shoulder. It began right after I finished so I assumed it was a strain and decided to take a break from swimming and continue the other tri legs. I've swam maybe 2-3 times since then with each swim being a catastrophic failure due to the pain.
I breathed on my right side only during the race and believe that overstretching my left arm stroke while taking longer breaths for 6 hours did some damage. If I had alternated my breathing I don't think I'd be in this mess!
I'm going to visit my doctor this week but would love some input. Thanks!
