i have had a constant dizziness for the past 6 months, and i have had all the tests from 2 ENT's, 2 Neuros, blood tests, ENG, MRI, tilt table, more., they have been unable to find anything. my symptoms are dizziness mainly when standing, but also when sitting if i am doing something that requires alot of thought or movement. It is not a spinning vertigo more of just a spacy disoriented, lightheadedness. movement makes it worse. i feel motion sickness sometimes. it is like all the signals are not processing right in my brain, and i feel more movement than there is. especially when i am visually distracted. My other symptoms are muscle spasms, hand tremors, a wierd vibration in my legs and sometimes arms, and some slight visual symptoms like sensitve to light and sometimes if i stare at writing it seems to vibrate. My docs have all attributed it to anxiety, because this all started after a panic attack that sent me to the ER, sometimes i believe it, but i am not stressed all the time. 2 neuros say its not MS or anything bad. does any one have any ideas? thanks
