paralysis?

[ethic]

Ok, I've been trying to OBE for about 21 days, i do lying down on my bed, after relaxation i go through the breath awareness until, I think, I achieve some degree of trance, the problem comes when my left arm (yep always my left arm) begins to get heavier and I start to feel pain in my arm, it gets painful, i try to don't pay too much attention on it but it really hurts, I try to do some arm work bouncing on it (NEW) to see if it stops but nothing, it stops until I move it for about 1 minute or so, i don't have problems to move it. I have been experimenting this many times but yesterday was more painful. I feel numbness in my legs and right arm too, but feels really stronger in my left arm, at the point that i cannot continue even if I want to.
What's this?
Oh BTW, i could actually move my left arm if i will, my concern is the pain i felt, is this a kind of a paralysis ?

Have you tried changing position?
