I pulled a muscle that's right over my hip back in about april, and even with a month of not doing anything, it still hurts after a while of exercising, or even just walking a long time. I'm a gymnast and freerunner, I know I pulled it in gymnastics, but this has lasted months. My questions are, is it a permanent injury? What is it exactly? Recovery time? Do I need to see a doctor? It also started to hurt in the same area over the other side as well, is it related or are both just from stress? I can walk just fine, there's no stiffness or swelling, it just hurts like a pulled muscle, which is not only annoying but uncomfortable. 5 months for an injury seems like a very long time, anything I should really worry about? Anything else I should know?
