Still Pain

I woke up today and I am still in pain. The pain goes from my butt down my leg, into my knee and down into my foot. I went to the gym and talked to the trainer. He said that my muscle is really tight. I am not allowed to run until it feels better. So today I lifted, rode the bike, stretched, and got on the roller. It is definitely tight! I left the gym and went to get new running shoes. I have had my current ones for about 2 years and I am wondering if this is part of the problem. I went to Flying Feet - they are great! They take so much time with you to make sure that you have the perfect shoe. I ended up with these - hopefully they will help!
