My husband is having these 'episodes' where he stands up, and starts trembling, and either ends up back in his chair, or on the floor. He loses all control of his muscles. Saturday afternoon, he got up from our dining room table, walked about 10', stopped to stretch and blacked-out, it only lasted long enough for him to hit the floor and badly bruise and bloody his nose. He is being put thru all kinds of tests by a cardiologist, and a neurologist....He's supposed to have a tilt table test next week, but we found out that even though it's the ONLY place in Utah that does these tests....my insurance won't cover it and so we have to cancel it...it's too expensive....we are living paycheck to paycheck as it is. We are both terrified.
