my son is a 17 year old athlete, (basketball) he is currently 6-4 but I believe he is still growing some. He has had on and off low back pain for several months, and the only real relief has been when he grew 1/2 an inch. We have been to a chiro, Gp had exrays and an mri and nothing shows up, no muscle strain, no tendon or ligament strains nothing. Could this be growing pains?
