Question Title: exercise and migraines

On numerous occasions within the last 4 years I have had episodes of heat exhaustion typically characterized by nausea, light-headedness, disorientaion, tingling in the fingers, spotty & tunnel vision, and subsequent severe migrain headaches lasting for 3-5 hrs. This condition is brought on by moderate to heavy exercise, typically compounded by, but not limited to, hot and humid conditions. This occurs despite absurdly high levels of water intake. This is only brought on by heavy physical activity. I do have a history of dehydration and heat related problems despite water intake. My military career, as well as my interest in exercise and sports, is in jeopardy and would like to get a grasp on what is going on. Thanks for your time.

Dear Jason,

Occasionaly migraine headaches can be precipitated/worsened by physical activity; however,from your description, it sounds like as if there is a definate cause and effect with regard to your symptoms. Hard physical workouts (several hours and extreme conditions ie hot, humid etc.) can not only dehydrate a person but can also cause the loss of several important electrolytes and minerals. Water may not be enough. I would recommend a general physical exam and routine blood work. You may want to break down your workout time (3 one hr workout for example). Discuss this with your doctor. if you are interested in getting an evaluation at CCf call 1-800-CCF-CARE. Good Luck.
