I've had this problem among many others for a while now. I'll Just give an example of what it is that happens. I could be watching a dvd and when the picture suddenly stops, for instance when the dvd freezes. I get this weird and also horrible feeling in my head. I can't describe how it feels. The best word would be a lift in my head. Same thing happens when i'm listening to music. Only if it suddenly stops does it give me the lift in my head. So if its a vacuum turning off i'm okay, as it eases off as opposed to a sudden switch off.
I have a lot off other symptoms, many the same as anxiety symptoms. Some other horrible experiences when trying to sleep.
Though the symptom above is one I cant find anything about through google.
If anybody could help I would greatly appreciate it
