Let me share with you our teammates experience which engrained in me that the second my child says their back hurts, they aren’t moving until a spinal ortho familiar with gymnastics sees them:
For several months, on and off, this girl had back pain. Her mom thought an chiropractor and back massages would be the best way to go forward - she was still in compulsory, there was no real reason to imagine something would be seriously wrong. The adjustments made her feel better temporarily.
But the pain kept coming back, harder and faster. Until she couldn’t bend over without crying. Another month passes, she’s now been mostly unable to practice for 3-4 months out of sheer pain and her mom finally takes her to an orthopedic pediatrician.
3 spinal fractures at the age of 11. 18 months of 23 hour a day bracing. Forget gymnastics, she hasn’t been able to bend over to touch her toes! She couldn’t hold her baby sibling, who is no longer a baby. She couldn’t ride a bike! 18 months later and the last fracture is still in the process of healing.
Would the outcome have been different if she’d gone to a doctor 6 months earlier? Maybe, maybe not - but when you hurt your arm or your leg, you can still use the rest of your body. When you hurt your back, you are pretty much not going to do anything because everything puts impact on your back.
