hello, My husband is a 31 year old, active, healthy, male with no history of health disorders. He began having very sharp, intensley painful headaches lasting 15 seconds or less about 2 years ago. The hewadaches are unpredictable and widely spaced. Sometimes coming once a week, sometimes less than once a month. He has had a few minor neck injuries, where he was left with a stiff painful neck for a few days at a time. We feel that these may be related. His latest symptom is dilated pupils. We are not sure if these are all related, but very concerned. Thanks
