Im 16 years old, when i was fourteen i badly injured my right hamstring during martial arts practice, it hurt to walk, but nobody was there to advise me on how to properly recover. So i took a week off, and returned to practice and trained on through the pain, which was the worst thing i could have done, because now, two, going on three years later im still in pain because of this. my static flexability is fine for the most part, but my dynamic flexability has been greatly reduced, even jogging irritates my hamstring, going up stairs bothers me, anything where i contract my hamstring and then lengthen it again seems to bother me. every morning when i wake up, or if i sit around inacitve for too long ( even an hour can do it), i go to touch my toes and my hamstring literally cracks like a joint would. ive been out of martial arts and gymnastics trainig for two months already, also because i have torn cartilage in both my left and right hips. my left is almost better, my right doesnt seem to heel. just sitting down the wrong way can irritate my hips. ive gotten professional help, they told me that if all goes well id be better by this point in time, and for my hamstrings they told me to stretch… which i already do daily, so it did not help me much at all. i fear i wont be able to return to martial arts and gymnastics again because of these injuries. does anybody have advice or can anybody relate? thank you for your time, and thanks in advance to anybody who replies.
