Without the ability to examine and obtain a history, I can not tell you what the exact cause of the symptoms is. However I will try to provide you with some useful information.
Dizziness has many different causes and people can describe dizziness differently. Some may say they are light-headed, others may say they are imbalance, while others may say the room is spinning. I am going to assume you are in the room-spinning category, which is also known as vertigo.
There are two categories of vertigo: peripheral (i.e., from the inner ear and nerves) or central (i.e., from the brain). Since you say you have a labyrinthitis, you were diagnosed with a peripheral vertigo. The most common peripheral vertigo is a result of inner ear particles moving out of place. This condition is called benign paroxysmal positional vertigo. It is easily treated with bedside repositioning maneuvers. I am assuming you had the Dix-Hallpike and perhaps Epley maneuvers performed when you first were diagnosed to rule this condition out. These are the diagnostic and treatment maneuvers.
Most all types of vertigo can make you nauseated. The sudden rise in temperature or flush and the headache may make the vertigo related to another condition. One condition that can cause headache and vertigo with an aura (i.e., the flushing sensation you describe) is a migraine. Do you typically have migraines? Migraines are usually one sided, throbbing headache, with nausea or vomiting, and perhaps light and sound sensitivity. If the vertigo is due to a migraine, it can last up to a few days. Have you always noticed if you get a headache with your vertigo? It is also important to realize that the nausea and vertigo can still be from a migraine even if the headache does not occur.
It is important that you should discuss your vertigo changes with your physician. If they feel your symptoms may be from a migraine, it may be worthwhile to start a calcium channel blocker such as verapamil.
Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.
Thank You for your advice. I am now taking a calcium channel blocker called cinnarizine I hope it works.
