The pain seems to be located on top and in the front. As the day has progressed, it has become less sharp and more dull. I did some biking & running this morning and it feels OK right now.

I am swimming freestyle, although on Monday I tried backstroke for the first time in years. When I swim freestyle I have a strong tendency to want to breathe on my left side, but I have been practicing bilateral breathing and did this on Monday during my freestyle workout (which was only about 1300yd). Fishing is spin and I have kind of a sidearm cast.

I don't know if this matters at all, but I played softball for many years as a child/teenager, but haven't played much since. This is my throwing shoulder and I never had any problems with it that I can recall. I guess my point in mentioning this is that my shoulder was used A LOT back in the day (which really wasn't that long ago I guess, I'm 26).
