My 10 Year Old Son Plays Soccer On Turf And

My 10 year old son plays soccer on turf and basketball. He has been complaining of pain in his big toe. His mother took him to the Dr for x ray and exam. She is telling me the dr said his toe was jammed. He also said that continued movement is the best fix for the problem and that continued playing of his sports will not cause more injury but speed up the healing process.
True?
