Okay, this is too weird. Maybe I need to increase my Gabapentin? I'm only taking one 300mg at night now. The last couple of days I've had this extremely odd and very unpleasant sensation. Hard to describe but ... very sudden, very cold, almost painful feeling on the right side of my head, in the temple, ear, face area ... as if I've been hit on the side of the head with a large, icy snowball! It makes me jump, gasp out loud and grab the side of my head. It just happened again and I'm just lying here in bed. Anybody ever experience anything like this before? WHATIZZIT?!?
