Flickering vision and other symptoms - is it a brain problem?

[Reinicken]

I'm a 26 year old male in the northeastern USA.  For the past 10 months I have had the following symptoms, most of which have gradually been getting worse:

(1) flickering / spotty / pulsating vision - i.e. looking at a white wall gives me mild moving flickering dark spots, looking at a dark wall gives me the same except the spots are light.  these are not floaters - their edges are very indistinct and i can see through them very easily.  this is more aggravating when i am trying to read text, but it is always there.
(2) a more constant dark spot in the very right side of my left eye's field of vision
(3) occasional ghosted text in both eyes (intermittent bilateral monocular diplopia??
(4) occasional blurry vision
(5) frequent general out-of-it feeling: i feel tired all the time, have constant mild cold symptoms, occasionally feel disoriented, lightheaded, nauseous, or have an upset stomach.
(6) frequent hives

here's what i've done so far to check:
(1) GP has standard bloodwork done and resting EKG done.  everything is fine.
(2) Ophthalmologist examines eyes, says everything is fine, implies that maybe something is wrong with my brain.
(3) Neurologist does exam and MRI of brain, says everything is fine.
(4) Neuro-ophthalmologist does eye exam, says everything is fine.  Tells me I should see a psychiatrist.
(5) Allergist cannot explain hives - allergy skin test is negative

My questions and insights:
(1) Could this really all be stress / hypochondria?  If so, what can I do about it?
(2) Over the past five years I have had unprotected oral sex with about 4 different people.  Could this somehow be HIV or some other STD?
(3) I've gotten sick this year more than normal.  Six months ago I had the worst diarrhea of my life, and three months ago I had a week of shivering and night sweats, which I've also never had before.  I assume this was just a nasty flu - but could this all come down to some disease like Lyme Disease, Diabetes, or Encephalitis?  Would my normal blood work have indicated any of this?
(4) Should I go back to the neurologist and insist on getting an EEG to rule out other brain-related things?  Should I repeat my MRI?
(5) I've also had a sore neck for the past 5 years and occasional unexplained chest pains (doctor says it's just stress).  Could all of the vision issues somehow be related to disrupted blood flow to the brain or pinched nerves in the neck?

Thanks for the help!

Hi,

I have similar symptoms...

Do you think something like this can be migraine-related?

Can I ask about your progress?  Have you got this resolved?  Where are you right now with this?

Any info would be greatly appreciated.
