Daniel is a 13-year-old boy from the United States who has been suffering from severe headaches for years.He has complained of intermittent,sporadic headaches,both in the front and back of his head,since he was in the third grade.The pain was so persistent that it prevented him from studying and playing normally like other kids when it attacked,even though he took painkillers every day-despite the fact that prolonged use can be detrimental for the kidneys,stomach and liver.
