question: My five year old sons has been getting headaches for about the past three weeks..He gets about 2-3 a week and they are usually in his forehead or brow line with some darting pain behind his ear..For the past few years he has complained that his nose feels weird so i took him to an ENT twice. The Dr. put a tube up his nose each time and saw nothing but I feel perhaps this could possibly be related to his headaches. I ,of course imagine the worst, should I be worried? should he have an MRI?
