I get terrible and frequent migraines and have done since I was 18 ( now 55...shh). They can last up to seven days and be triggered by anything from being cold, stressed ( which probably explains the frequency) to various foods, smells ( onions, perfume), anger, excitement, tiredness and being overloaded in general. Light catching my eyes does it too especially reflected sunlight in a flash. I've had a lifelong allergy to citrus and lemon seems to be 'hidden' in so many foods, I also find monosodium glutamate a huge no-no. I sometimes get migraines daily and feel worn out with them. I've often wondered if these are cluster headaches as they are supposed to be a very painful form of migraine. I've been taking 120mg of Propranolol a day for a few years as beta-blockers can prevent them but apart from putting on a shed load of weight it hasn't made much difference, but then I think they might be worse than this if I stop them. I always find it helps to keep my head warm when suffering from migraine and wrap the first thing I can grab that's soft around my head and cover my eyes. No medication has ever worked except one and the side effects were frightening.
I get no warning signs but my migraines are accompanied by numb mouth and nose, heightened sense of smell, tinnitus, slurred speech, distorted vision (everything looks in 2D, but then it does a lot to me anyway) and they can also be one-sided (usually the right) or all over and down to my shoulders.
I'd love to look at the sunset but I can't even with sunglasses on because that seems to really trigger them.
