Different possible causes

Detailed Answer:
Hi,

Thanks for using healthcare magic.

It is possible that the dizziness and nausea may be related to a condition of the inner ear. But, would also like to know regarding your menstrual cycles and if you are sexually active or not.

These are the most common causes of dizziness/vertigo (feeling of room spinning or person spinning).
These conditions are BPPV (benign paroxysmal positional vertigo), meniere's disease and vestibular neuronitis.

These are not life threatening conditions but the dizziness/vertigo and nausea that they cause can cause significant discomfort.

(1)In BPPV- the episodes tend to be worse with specific positions. They tend to last for a few seconds to minutes.
Diagnosed when doctor performs particular maneuvers in the office.

Treated by the doctor doing a maneuver called Epley's maneuver.

(2)In meniere's disease- may be associated with hearing loss and tinnitus (abnormal noises in the ear eg: buzzing
Episodes lasts for minutes to a few hours (rarely)

Treated with low salt diet and in some cases medication

(3)vestibular neuronitis- episodes last for hours at a time

Treated with a short course of medication such as meclizine, dramamine, diphenydramine
These are antihistamines but are helpful with dizziness and nausea.

You need to consider visiting your doctor for an assessment. He or she would examine your ears, perform particular maneuvers to see if BPPV, check balance and coordination.

A short course of the medication mentioned can be used.

If it is BPPV then the epley would be done in addition to the medication.

Summary: (1) may be related to inner ear disease
(2)physical examination would determine the cause
(3)medications such as meclizine, dramamine or diphenhydramine used for the short term, may help
(4)if it is bppv, then epley maneuver will help
(5)if menieres- low salt diet may also help

I hope this helps, feel free to ask any other questions
