Something I learned recently is there are 3 different types of photophobia associated with #migraine.

Type 1 is when light worsens migraine headache pain. This is due to the receptors in the eye then going to the thalamus and being transmitted out to the trigeminal nerves 1/4
which transmit pain receptors in the face and head. Therefore light makes the pain worse.

Type 2 is increased sensitivity to light. Light seems brighter but it doesn’t make the headache worse. This is due to dysfunction in the brain pathways that mediate response to light. 2/4
Type 3 is light causing eye pain which has to do with neural pathways within the eye itself.

This is important for clinicians to ask about these because someone may have photophobia but not realize it. And this may contribute to them not getting a migraine diagnosis. 3/4
Just something to think about when asking about photophobia or educating a patient on it. #LearnAThing #MedTwitter #NeuroTwitter #HeadacheMedicine 4/4

If you’re having a migraine prodrome clap your hands! 👏🏽👏🏽 If you are dealing with severe fatigue and irritability and that anxiety knowing a migraine attack is about to happen but you don’t know when and you’re out of your usual rescue so you’re also sad, clap your hands. 👏🏽👏🏽
It’s me. I’m clapping my hands. #migraine #NotJustAHeadache
And the attack is here. I have one charge left on my nerivio and my new one hasn’t come in yet. Praying I caught it early enough that I don’t need much more. 😫
