I woke up on Saturday morning to find I couldn't lift my hand up with my when my palm was facing downwards. No pain, no numbness, just intermittent pins and needles or tingling and no power in the upper side of my wrist.

I can move my fingers and grip, though not as powerfully as usual. If I put my palm facing upwards I can lift my hand up. My coordination is not as good as normal, which isn't saying much.
