on a few occasions I would wake up in the middle of the night not being able to move one of my legs (as if it was asleep), other times I would wake up in the morning with my entire arm being numb. This morning I woke up and my entire right leg was numb, and I had trouble moving my left arm. After about 2 minutes I deveoped pins and needles in my leg and slight tingling in my left arm... then everything was back to normal.

is it sometimes normal to experience limb numbness/tingling in the morning when you first wake up? or is this indicative of a serious neurological disorder?

by the way, I'm 21, no history of stroke, and a normal MRI of the brain as of April 2008
