Only vaguely have had something similar - whether it was attributed to MS not sure sorry. I had crawling effect up near my hairline on my face - it always felt like I had a bug crawling in my hair
Before I was diagnosied I use to suffer from a weird sensation in my groin area around my hips that made me feel like I couldn't keep still and laying in bed was something that drove me insane. It was like muscles couldn't stand being still - Maybe like restless legs but I had it in my hips!!
I can still see myself now sitting in the doctors trying to explain the symptom feeling like a real prat! Then I was dx and I felt that I had an answer, well sort of. MS can do some weird stuff sometimes is all I can say.
