T.,
At first blush, I could'nt help but think of the situation I am in with my 14 year old son. You should definately have her seen in order to avoid any "real" problems in her future. It could be nothing, but knowledge is power! My son is very active in many sports and had been complaining of mild back pain for a few months before he had some crippling pain suddenly after just a few quick moments on the basketball court one day (about 1-2 months ago). Turns out he has a fracture on his spine called a "pars defect". Google it if you are interested. He is currently working with a physical therapist at TX Sports Med in Tomball. Apparently, his PT has numerous patients in that age group with this same diagnosis (you will understand why if you read more about it online). I hope this is not the case with your daughter, but it is repetition/sports driven and usually happens to "kids" between 13-18 if I remember correctly. If you want to rule it out, she'll need a series of Xrays and possibly a bone scan and/or CT scan if a possible fracture shows up on the Xray. Feel free to email me directly if you need more info. I don't have a DR to reccommend in the area... I took my son to a spine specialist down at the Med Ctr. The Dr we went to does not normally see "kids" but took us because of the referral of my brother in law - who is also an orthopedic surgeon, but in FL. I do know that TX Sports Med in Tomball works closesly with many orthopedic Dr's... you could call them for a referral. Good luck and i hope it's nothing!
