Wow...I can't even describe the pain I felt and am feeling. I was swimming at Bally Total Fitness and I wanted to push really hard one lap. I did that as hard as I could, half way through my leg just cramped up so hard I almost drowned right there thank God my dad was with me. My leg felt like it was being squished together, I couldn't move it and it felt like something was stabbing me. Right now I can't walk without help and I'm really scared for my well being. Will this go away? Why am I getting this, I am very healthy and athletic. What should I do?
