HELP!!!!! I NEED AN OPINION! WHAT DO I HAVE?????!!!!!!!!!!!?

Ok, so here's the deal. I run alot, and about a month ago, my calf started hurting really bad. I don't know what it was from. For awhile, the pain stayed the same. I had pain in the middle of my calf and my achilles. A week ago, my coach said my achilles was swelled and I have swelling in my calf (also said last week.) Now, the pain has gotten MUCH WORSE. It hurts to run fast and I'm having problems in my work outs. I don't know if I have a pinch nerve or a torn muscle or pulled or something. It hurts to walk up stairs and run, it's sore when I walk. I ice it in a bucket of ice water three to four times a day, but it is still not any better. What do you think it is? PLEASE HELP! PLEASEEEE!!!!!!!
