Vertigo, or dizziness, usually results from a disorder in the peripheral vestibular system (i.e., structures of the inner ear). Dizziness also may occur as a result of a disorder in the central vestibular system (i.e., vestibular nerve, brainstem, and cerebellum). In some cases, the cause of vertigo is unknown.

Go see a doctor because something is wrong with your inner ear or ear drum. For some reason, the ear is one thing that keeps you in balance and if something is off in there, you will loose it. Most of the time, you don't get vertigo but it can happen once in a while. I had a lot of wax build up in my ear once. Yes, I would clean them out with q-tips, but this was a hard ball of wax in the ear canal next to my ear drum. Well when the dr. removed the wax, I was dizzy for a couple of days.

Vertigo is a sense of dizziness and disorientation, and it often arises due
to problems with the vestibular system. Your vestibular organs are
contained in two structures called the labyrinths, which are often referred
to as the "inner ear." There is one labyrinth on each side of your head,
located near your cochlea (the primary sensory organ for hearing).
The labyrinth is composed of two principal organs: the semicircular canals,
and the otoliths. Each semicircular canal consists of three "loops"
organized at right angles to each other. If you imagine an X-Y-Z set of
axes, one loop lies in the XY plane, one in the XZ plane, and one in the YZ
plane. The canals are, indeed, filled with fluid. A specialized expansion
at the base of each canal contains neurons with little hairs (or cilia)
sticking into a membrane. When the head moves in an appropriate fashion,
the fluid in the canals move accordingly. This fluid movement causes the
membrane to bulge in the direction of head turning, which bends the cilia of
the hair cells. When the cilia bend, ion channels in the neurons open or
close, which sends an electrical signal to other neurons. So, the
semicircular canals manage to translate head movement into fluid movement
into electrical (ion) movement. The semicircular canals are most sensitive
to head rotations, like looking to your side.
The other labyrinth organ is called the otoliths, and their structure is
slightly different. The otolithic organs are located in the same part of
the body, and also contain hair cells with their cilia embedded in a
membrane. Instead of containing fluid, though, the otoliths contain a rocky
sheet of calcium carbonate crystals (that's where the otolith gets its name:
oto + lith = ear rock!). When the head tilts or is subject to acceleration/
deceleration (like in a car or an airplane), the rock moves, and the hair
cell cilia are bent. Again, this sends an electrical signal to other
neurons.
By letting your brain know how your head is moving, the labyrinths help you
maintain a sense of orientation. They also keep your gaze fixed as your
head moves, so that your eyes can maintain a continuous picture of the world
around you. So, when they're not working properly, patients experience
disorientation, and may also have inappropriate eye movements.
Vertigo is thought to be caused by a disruption of the various components
that make up the vestibular system. It is known that certain antibiotics
can disrupt hair cell cilia, causing vertigo and hearing problems (because
hair cells in your cochlea are similar to hair cells in your labyrinth).
Alterations in the fluid composition or pressure could produce vertigo, as
well. Another idea is that particles of the otolith could become
mislocalized, resulting in inappropriate stimulation of hair cells

I had vertigo due to an inner ear infection, which caused my equilibrium to be off-balance. You have to be careful that you don't fall and hit your head or something. Your doctor may be able to give you something for the dizziness. Hopefully whatever is causing it will go away soon.

possible inner ear infection. Also, many medications can cause vertigo, as well as low blood sugar.
