I've been suffering with Migraines since I went through puberty at 11yrs old. Once a month,after my menses,I would begin to develop a migraine. The pain lasted anywhere from 24-72hours.During this painful episode I would experience light sensitivity,nausea,dizziness,and irritability to loud noises. My physician experimented with Rx migraine medication,Acetaminophen,Ibuprofen, Naproxen,Advil,Caffeine,and even Narcotics. Nothing worked. The migraines began to affect my work performance at least once a month,and I was at my wits end. I went to Rite aide one day before work,and purchased multivitamin supplements to begin taking. I was short on time,so I stashed the bottle in my purse. Later on at work,I felt a migraine coming on,so I took Advil and a Multivitamin. Miraculously, he pain went away! In the following months I experimented with Just Advil or Just the Multivitamin. I had a hunch that something else was going on so my doctor agreed to get blood work on me. As it turns out,I am Anemic,and when my menses ends,my body is low in iron. Ever since I was diagnosed,I have been able to prevent the migraines,as long as I take my vitamins . If any males/females are suffering from chronic migraines,please get a complete blood count,to rule out whether or not your iron levels are low. It just might help tremendously. Good luck!
