I'm a senior in high school and I've been experiencing dizziness, regular headaches, and every now and then weak neck muscles (like my head is too heavy) for a year now. At first I had chest pain, but that went away after about 2 months. I've had every test possible done (CT scan of sinus cavity, wore a heart monitor for 24 hours, MRI & MRA of brain, EEG test, vestibular test). All tests turned out fine. I first went to my primary doctor and they gave me allergy medicine thinking it was that and it didn't help. From there I went to an ENT and done the CT scan and everything was good. After that I went to a neurologist and done all of the other tests. I went to the cardiologist and everything was fine there. After all the tests were done, the neurologist gave me medicine specifically to treat the dizziness and it didn't help. After that they gave me an antidepressant to see if it would help and it didn't. (They gave me the antidepressant because I told them earlier that year my house had burnt and we just moved back in after we remodeled/rebuilt and the dr said that caused my brain to do something different and cause the dizziness because I wasn't used to the changes) I don't know what else to do. I get nervous and can't drive because I feel too dizzy. It gets worse if I get hot. If the room is cool or cold I'm fine. The heat makes me feel more dizzy. Could it be anxiety? I'm out of ideas. Anybody got any suggestions?
