I'm a highschool girl and pretty athletic. I swim, run track and field, and run cross country. My real love is track and field. The season started about two weeks ago, and I have been going to the gym in the morning 3x a week. I end up going to the gym on two track days. Last Monday (the 23th), I was running 800's on the treadmill, and my leg was a little sore when I got off. I didn't think much of it, just stretched out. It mostly stopped bothering me but didn't feel totally normal. I missed track that night, but I had it on Wednesday. As I was sprinting 400's, I felt this ripping pain in the hamstring of my right leg, the same place it had hurt on Monday. I kept running, but afterwards it hurt so badly I laid on the ground for about five minutes. It was still hurting afterward, but I kept running for 3 more 400's. Today, I had another practice. I didn't run at all, just stretched out. I went to practice long jump, and just sprinting to the board hurt. I have a track meet on Saturday and I don't know what to do. I can still run, but I'm not anywhere near my best when my leg isn't hurting. When I'm sprinting, it's all I can focus on. I have a doctor's appointment today for some shots, and I don't know whether or not I should mention my leg since it's only been 5 days. It's a sharp pain in my hamstring, near the back of my knee. I looked up pulled hamstrings, but I'm not sure if it hurts badly enough, although it is very swollen compared to my other leg. What do you guys think? Thanks!
