Hello...I've been having episodes of sorts normally when I go to stand or standing it's almost always the same. first I lose my vision like the lights go dim sometimes i lose consciousness when it subsides I find myself shaking I am aware but I can't control my limbs I get a tingling sensation as I regain the use of my limbs....I've been dealing with this for some time now but it's never been as bad until here recently. I appreciate any thoughts on the matter thank you
