hi - i am a 28/f, 145lbs, 5 5 with a history of strokes (all small, nothing residual - last time when 19, followed by repaired PFO). my limbs regularly become numb while sleeping. normally i would not think much of this, but this morning i woke up and the right side of my face was numb, and my right arm and leg were tingly (i was sleeping on my right side). it scared me, but i thought it was just a circulation issue and went back to sleep after half hour or so. however, my face still feels funny, as do parts of my arm. at what point do i need to seek medical help?
