I am a 26 year old mother of a 3 yr old and 8 month old. I have been having a stange feeling all over my body; but mostly in my head, arms and back. I cant describe the feeling very well, but it feels like waves are rolling over my skin. It happens when i stand up, move my head or eyes and especially when i am walking. I checked my blood pressure and it was 133/88.What could be going on?
