I saw this thread posting, and decided to add to it as much as I am sure of.
Last week, I got up to go to the bathroom during the night. Just as I finished, my legs suddenly went out from under me, and I took one hell of a fall. Thank God, I didn't hit anything but the floor, although ceramic floors ain't all that soft. Sheesh!!! It woke my wife up, and she naturally came running. There isn't enough space in this small bath for two people to pass each other, and she isn't strong enough to pull me. So, I had to inch my way along out of the bathroom until I could turn over, and then proceed to pull my self over to the bed. What surprised me was that my arms were almost as weak as my legs. It took everything I had to pull myself out of the bathroom. Admittedly, I weigh 228, but that much weight has never stopped me from doing pull ups, and many other exercises. So, my point is, whatever made the legs let go, did almost as much damage to the arms as well. After about 15 minutes, I was able to use my arms, assisted partially by my legs, and pull myself back onto the bed. In about half an hour, everything was pretty much back to normal.
I do however, have the main arteries in both my legs stopped up from the hip, to the knee, so that didn't help. But, the scary part is that I didn't even feel it coming on. And, I never got dizzy, or anything.
As they say, that's my story, and I'm sticking to it.
Anybody have any idea as to the sudden weakness that comes from NP?
