Still can't swim!

I have not been able to swim since Sunday when I fell and injured my shoulder I have been resting and my shoulder still hurts but I thought I would try and swim today. It was a nice day so I decided to ride the 4 mile ride to the pool and as I was riding I could feel that my shoulder was getting a little tight. Great I though to myself, if it is bothering me know it will be worse in the pool.

I got to the pool thought positive thoughts jumped in the pool tried to swim 25 yards and there was pain. I kept trying thinking it would loosen up but no luck. I ended up swimming a total of 200 yards and getting my money back as I could not really swim. My first triathlon is 2 weeks away, please please should stop hurting!
