So I'll give a lot of detail about the incident

So I was out exploring the forest behind my house for like an hour or so. So I see a little stream and I try to jump over it. I long jump over it. It was about 13 or so feet. I made the jump. I landed and there was a pop. So I stumble down and lay there for about 3 minutes holding the right side of my calf. It is on the right side of the calf in about the middle region. So I stumble back to my house. Up and down Hills. I walked about a quarter mile to get home. It took me about an hour. I have been icing it and laying down since. This all happened about 2 and a half hours ago. So any ideas of it it just a strain or pull? There was a pop so it is kind of scaring me. Any ideas?
