So I've got a bit of a problem. I constantly have this pain in my hips when kicking, and I can't kick higher than my ribs. However, after doing some dynamic stretching and side splits, the pain completely goes away and I can throw head kicks at a slightly shorter person than me. After about an hour, the pain comes back and the same thing happens until I stretch again. What it this? What should I do about it? Just give stretching a rest, or what? Edit: They especially hurt when I start to do my daily stretching.
