my experience with migraines come with some pre-auras light sensitivity etc. followed by onset of pain immediately right after these occur but i've had some migraines that just start with pain and nothing more. then i've also had pain migraines that are followed by partial temporary vision blindness. everyone has different body responses. it's best to discuss these differences with your physician just in case there are any other causes of individual symptoms & opinions on how to deal with each type.
does a migraine always include pain or can you just have light sensitivity?
