Woke up in the night to go to loo, swung legs out of bed, started standing, then collapsed in a heap on the floor. Right knee would not support weight at all. If I locked it out straight I could hobble along, but any normal walking resulted in falling over. No pain, no pins and needles, no numbness.
What the bugger was going on? I used to fall over a lot due to sciatica when I was pregnant, but that hurt. This didn't.
Quite often my left arm doesn't work at all for a minute or two after I've woken up, regardless of the position I've slept in.
Anyone else had this?
