I was halfway into my 30 second sprint on my second interval, and my calf just started to cramp and hurt like crazy. I finished the last fifteen seconds of the sprint on a very painful calf. Anyway it's damaged somehow and I'm not sure what it's called. Did I pull a muscle or what? It doesn't feel like a tendon it just feels like someone hit my calf with a bat, right below the gastroc, about halfway up on the soleus. It's a little sore to flex but if I try to give it any tension like standing and flexing it rising up on my toes or really trying to push off with that foot it kills. How long will I have to recover before I can sprint again? I'm super pissed about it because I was just starting to get stronger at the interval sprints. I don't want to be out for like two or three weeks until it is strong enough again. I have goals and this really messes with the plan. What are ways to rehab it quickly. How do I properly determine if it's is indeed a muscle pull and not something else?
