I keep pulling hamstrings and i keep getting injuries- im only 15... any help?!

i've always been very flexible but in the past 6 months i have had a torn hamstring (almost a hip pointer) and i went through theropy for all of last summer and the first day back i had conditioning for basketball and then i get a condition in my heel (which i went to the doctor and found out it was Severs desease, which is similar to Oshgood Slaughter - in the knee, but severs is in the heel) and then after 3 weeks of sitting off of that heel i come and the first day back from that, i just started jogging before conditioning and slowly my other heal started hurting and by the middle of practice i couldnt run (its probably severs - in the other foot) and then one day i tried to play through it (this was about a week after sitting off of it) and i pulled my other hamstring (it just got tweaked when i ran, then on the side i tried to stretch it but every time i stretched it, it only hurt even more, and its not that bad anymore (its been about maybe 2 weeks) but occasionally it will hit me if i bend over to maybe pick something up- it will shoot in my upper hamstring... i really dont no why i keep getting so many injuries and my friends/coaches (probably coaches) think im faking everything (btw i also grew like 6 inches in about 5 months - about 3 months before my first hamstring tear... and my doctor suggested that my bones are growing faster than the muscles, and my muscles dont seem tight but idk... i stretch pretty much every night but still . btw im 15 and 5' 7'' any help please...Health Question & Answer
