 [ Symptoms ] about 5 weeks ago my 40 lb son fell on my left foot i had an x ray done and it showed no broken bones [ Disease ] hi from the history it seems that there may be a ligament injury if not a fracture even though you get a mri done the initial line of management would be a plaster boot so i would suggest you to apply a plaster boot for 3 weeks with complete bed rest and non weight bearing this will heal up the underlying injuries thanks
