I not only get the scalp pain but when I brush my hair I get goosebumps/shivers just from the touch. BTW...had to have the pony tail cut off (donated the hair to cancer) because the doc said the weight of it was aggrevating the head sensations and TMJ. It helped with the TMJ but I still get the shivers when I brush my hair!
I got my hair cut much shorter because of the scalp pain thing, it would realllllly hurt. I, too, wore a ponytail alot or the half up half down pony thingo. Sometimes the scalp pain would give me a major headache. Hubby liked my hair long but it had to go.
I don't get leg twitches, but I do get them in my arms and my eyelid (usually the left eye), very annoying and after a while the area that twitches starts to hurt. I had that twitch in my eyelid for about 4 - 5 months, before I left my job. about 2 months after I've left, it stopped. I think it was stress. One of my friends that I have always suspected to have Fibro, complains about eyelid twitches too.
Hope you feel better soon!!
