What Causes Recurrent Pain On Right Calf Caused After Injury?

I m a professional dancer, mostly in ballet. I have had an injury in my right calf off and on for 10months. The first injury occurred in April 2015. It was a small insignificant jump. I felt a kind of pop. It was a deep pain. I couldn t dance on it for a day. I walked with a limp, then felt normal after several days. There was no incident since then until the first week of December last month. This time I was doing a big jumping combination, but did not feel it happen. In a simple transition step, I noticed pain and finished the combination, then sat out for the rest of class. Again, it took several days to feel normal. That same week, I felt it pop during an insignificant jump. I was limping up until my performance, which was two days after that recent occurrence. I performed. Perhaps 800mg of Ibuprofen plus adrenaline got me through. I went through the last week of December up to this past Monday with no issue. I felt the pain again, though without the violent popping sensation, and not as severely painful. My question is: Do I have a calf strain? Or do I have repeated cramps, or some other condition? Can I treat it myself? My insurance doesn t kick in until April. Thank you, Alfred
