Thank you all for your replies and tips
I've had the 'deep sleep' in my limbs for many years. I wake up with a sleeping limb and it will take forever to wake up.
This is different though. I lay down on my back, arm totally free. 2-3 seconds later, my entire arm goes numb. Different numb cause I can still feel it when I touch that arm with my other hand.
I have other neuro symptoms too. Sometimes one side f my face or torso goes numb for a day. But the numb to the touch. Lots of strange feelings like the raindrop or running water feeling on my skin. Black outs too, my eyes and eyelids doing strange things, etc.
And the position of my back slightly changed because of those 2 factured vertebrae from last year. That was lowest thoracal and first lumbar, much lower, but it will probably change everything. It's strange though that it would take so long to occur. The fractures happened 16 months ago.
