It has to be part. A lot of us who have fibro also have migraines and the hair hurting seems to be part of it.

Try Maxalt or Rizatriptain. They really help but you need a prescription. Promethazine is good for nausea which might come visit with the migraines.

Even my hair hurts so bad , I've lost large spots of hair when the headache is over.Its a relief after is does fall out it stops the burning

Yes I have the scalp soreness, I think that it’s part of fibromyalgia. It moves to different places on my scalp. Sometimes it is sore in the crown , then it moves side to side. It is unexplainable. Hope you are better, Be Blessed!
