My son was awarded a 3-year army ROTC scholarship. He just found out that he was medically disqualified for headaches. However his medical records show that his migraines are resolved and he's not on any medication and only indicated on his paperwork that he has one regular headache a year for the past 2 years which is treated by over the counter ibuprofen. He's very confused why this would medically disqualify him. What do you suggest that he gets from his doctor to help in the waiver process?
