How can I tell if my cat ear problems are due to an ear infection?

What causes cat ear infections? Cat Skin infections?
My cat was recently diagnosed with a severe inner ear infection. She is circling & stumbling. I can tell she is in an extreme amount of pain. The vet prescribed an ear drop & Baytril tablets. She also recommended having her sedated and her ear flushed (her ear is so goopy they can't see in it very well & suspect a polyp. Well they vet can't get her in for 2 wks for this. I am so worried & she is miserable. Will having her ear flushed give her any relief? I was thinking of asking to vet to suggest somewhere that can get her in sooner. Or should I just stick to the Baytril & hope it works quickly? Please help, I hate seeing my cat so miserable.
Other contributing causes of ear infections in cats include:
After the ears are cleaned, an actual ear mite treatment can be used. It is important to also use a flea control medication on the rest of the body at the same time. This is to take care of any mites that have migrated to some place other than the ear. Doing this will lessen the chances of a recurring infestation.

Indoors, he points out, you must always be aware of your cat’s hearing loss and adjust your behavior accordingly. He suggests the following: “Avoid startling the animal. Never approach it from behind without signaling your approach. Clap your hands sharply or stomp on the floor. The vibrations will let the cat know that you’re nearby. If it’s asleep on the sofa and you want it to wake up, move a pillow. The cat will pick up those vibrations, too.”Although most cats will go through life without experiencing a serious problem with their ears, owners should know that a variety of conditions—including congenital defects, infections, trauma and changes—can be extremely painful and may compromise an animal’s hearing. Most feline ear disorders are readily treatable and will not result in permanent hearing loss, notes James Flanders, DVM, an associate professor of surgery at Cornell University’s College of Veterinary Medicine. However, some conditions may render a cat partially or totally deaf, especially if they remain unrecognized and untreated. Among a normal, healthy, and properly cared-for cat’s many distinctive attributes is its astoundingly acute sense of hearing. While the human auditory system is capable of detecting sounds ranging in frequency up to about 20,000 vibrations per second, cats typically can sense sounds pulsating at 60,000 vibrations per second or greater. This impressive acoustic sensitivity has been honed over the ages to serve a cat in countless ways—signaling the stealthy approach of a dangerous predator, for example, or detecting the underground movement of a burrowing rodent.The most usual mite to infest cat's ears is the Otodectes Cynotis. This tiny (around 4mm,) eight legged parasite is in fact not exclusive to felines and can migrate from animal species to animal species. Ear Anatomy

A cat’s ears, like those of other mammals, are made up of three structural areas: the outer ear, middle ear and inner ear. The outer ear consists of the external earflap (), and the ear canal—a narrow tubular passage through which sound vibrations enter the ear from the outside environment.Congenital Conditions

Some feline ear abnormalities are genetically transferred from parents to offspring. Among these is an inherited condition known as “fold-ears,” in which the tip of a cat’s pinna is bent sharply either toward or away from the skull. This bizarre condition is not often associated with hearing loss. However, cats whose ears are unusually distorted in this manner frequently experience accompanying skeletal problems that may have troublesome consequences.
