...but I think I'm more like Leia right now or something. Chewbacca. Something. I'm certainly no Master anything when I'm stuck at home, fighting dizzy spells. I haven't even thrown off a mound. I haven't taken bp. I haven't done anything. And I won't do anything for another five days or so. Which is insanely frustrating. For anyone that doesn't know, here's a more detailed description of vestibular neuritis:
Vestibular neuritis causes dizziness due to an viral infection of the vestibular nerve. The vestibular nerve carries information from the inner ear about head movement. When one of the two vestibular nerves is infected, there is an imbalance between the two sides, and vertigo appears. Vestibular neuronitis is another term that is used for the same clinical syndrome. The various terms for the same clinical syndrome probably reflect our lack of ability to localize the site of lesion. The term "neuritis" implies damage to the nerve, and "neuronitis', damage to the sensory neurons of the vestibular ganglion. There is actually evidence for both. There is also some evidence for viral damage to the brainstem vestibular nucleus (Arbusow et al, 2000), a second potential "neuronitis". As the vestibular neurons are distinct from cochlear neurons in the brainstem, this localization (as well as the vestibular ganglion) makes more sense than the nerve in persons with no hearing symptoms. Nevertheless, if the nerve were involved after it separates from the cochlear nerve, neuritis would still be a reasonable mechanism. Prior to death and autopsy there is no way to make a clear distinction, and the present favored term is "neuritis."
The symptoms of both vestibular neuritis and labyrinthitis typically include dizziness or vertigo, disequilibrium or imbalance, and nausea. Acutely, the dizziness is constant. After a few days, symptoms are often only precipitated by sudden movements. A sudden turn of the head is the most common "problem" motion. While patients with these disorders can be sensitive to head position, it is generally not related to the side of the head which is down), but rather just whether the patient is lying down or sitting up.
(now you all know why I've been trying to stay very still and not move too much)
Acutely, vestibular neuritis is treated symptomatically, meaning that medications are given for nausea (anti-emetics) and to reduce dizziness (vestibular suppressants). Typical medications used are "Antivert (meclizine)", "Ativan (lorazepam) ", "Phenergan", "Compazine", and "Valium (diazepam) ". When a herpes virus infection is strongly suspected, a medication called "Acyclovir" or a relative may be used. Steroids (prednisone, methylprednisolone or decadron) are also used for some cases. Acute labyrinthitis is treated with the same medications as as vestibular neuritis, plus an antibiotic such as amoxicillin if there is evidence for a middle ear infection (otitis media), such as ear pain and an abnormal ear examination suggesting fluid, redness or pus behind the ear drum. Occasionally, especially for persons whose nausea and vomiting cannot be controlled, an admission to the hospital is made to treat dehydration with intravenous fluids. Generally admission is brief, just long enough to rehydrate the patient and start them on an effective medication to prevent vomiting. It usually takes 3 weeks to recover from vestibular neuritis or labyrinthitis. Recovery happens due to a combination of the body fighting off the infection, and the brain getting used to the vestibular imbalance (compensation). Some persons experience persistent vertigo or discomfort on head motion even after 3 weeks have gone by. After three months, testing (i.e. an ENG, audiogram and others) is indicated to be certain that this is indeed the correct diagnosis and a referral to a vestibular rehabilitation program, may help speed full recovery via compensation.

The person will probably be unable to work for one or two weeks. They may be left with some minor sensitivity to head motion which will persist for several years, and may reduce his or herability to perform athletic activities such as racquetball, volleyball and similar activities. After the acute phase is over, for a moderate deficit, falls are no more likely than in persons of his or her age without vestibular deficit (Herdman et al, 2000). Persons in certain occupations, such as pilots, may have a greater long term impact (Shupak et al, 2003)
So that's basically it. That's what's wrong with me. And it really, really sucks.
I'm off to do some light exercising; let's hope I don't get nauseous again.
