Re: Can stress cause dizziness?
Absolutely. I was getting dizziness attacks several years ago, where I would stand up and nearly fall down in a dead faint. I saw an ENT who called it "cochlear hydrops", or build-up of fluid in the middle ear. He said there's no cure, and it's often related to stress, but suggested I cut down salt in my diet. Well, I cut down salt and the dizziness went away.
I don't know if that's the cause of your dizziness, but it wouldn't hurt to cut back on salt. Also, please see my post under allergies, "How I got rid of sinus problems". This was a later problem involving my inner ear, not my cochlea, and went on for a long time & scared me to death, but I kicked it.
