Injury?

I was running yesterday at lunch and started to have this pain in my Achilles tendon like needles. I figured I would run through it and it would just feel better. Nah. Still painful today so I'm headed to the trainer to see what he can do for me. I hope It heals quickly since I'm enjoying running so much.

Edit: It's a strain, the trainer says. So he hooked me up to a muscle stimulator and let it work me for a while. The tendon felt much better when I left. Now I've got it iced for the night and I'm going back after work tomorrow.
