Weird tingly sensation...

Hey everybody!

Okay, here's my little health issue: The left side of my body is slightly tingly, and has been for about a day. Usually the base of the left side of my head tingles a little bit [I think I sleep the wrong way], but not it's down my arm and leg, too. I was wondering what you all think this might be? My boyfriend's mother is a nurse, and I asked her, and after ruling out a reaction to MSG, she thinks that I have a pinched nerve. I got hit in the head [right side] a few times last Sunday, and I was wondering if maybe it's related? Any help would be very, very appreciated.

Good vibes to you all! <3
