I think I have felt this “distortion” in the head before when I have been “sick” with other things, and I couldn’t put a name to it, either. The best I could explain it was that I felt like I had restless leg syndrome in my head, but if you’ve never had restless leg, it’s hard to understand THAT. It’s almost like someone is holding a feather right above your scalp and has every intention of tickling you with that feather … in about 4?months! Very weird sensation!
