I was on a training run about 3 weeks ago, exactly 1 week before my first race, and I strained the muscle below my right calf. So, during race week I took it easy and by race day everything was going great until the run when the injury came back. I had to walk/limp the last couple mile because the pain was unbearable. The following week after my race, the problem got better until today when warming up with a light jog, I felt a slight "pop" in my calf. I'm not sure if I tore the muscle or if I pulled it. Our medical insurance sucks from work with zero coverage for physical therapy, plus I have to get a referral from a doctor first. I don't want to spend $300+ to have someone show me different stretches and exercises. I'm supposed to do a sprint race in about a month, which I'm hesitating to do. I have 5 races scheduled, each about a month apart. Should I bag the first couple a let everything heal? Any suggestions on what I should do with the injury?
