Help. I've been going through a series of test and so far are are inconclusive. I have had an MRI, EKG, wore a holter monitor, blood work, am scheduled for a pulmonary function test, echo. My symptoms are dizzy, feel in a fog all day, slight to moderate headache that I wake up with every day, i feel shaky when I wake up and tired, I have heart palpitations (but nothing out of the ordinary) I sometimes wake up sweating and hot I get a zinging in my head that makes the foggyness worse and depending on how I move my head I feel more dizzy. Now I can simply be chewing and if my teeth hit it happens, i also have now noticed my ears ringing from time to time. When I'm watching tv or listening to the radio sometime just answering the phone it seems very loud. My doctor is trying everything and to no avail. I am frustrated walkin around in this fog. I do not feel like doing anything but sleeping all day one cause I'm tired and second cause I'm depressed. I get very stressed easily which affects my dizzy/foggy feeling. Since she is not sure she is sending me for numerous test and so far every test comes back normal. I know I'm not crazy something is happening. Please help if you can.
