kat, m'dear, I'm afraid you may have been taken. First, while it is possible to have a dislocation of the little bones in the ear (malleus, incus, and stapes, a/k/a hammer, anvil, and stirrups) as a result of trauma, the result would be a sudden loss of hearing, not dizziness, and it would be nothing short of miraculous if turning you from one side to the other would put them back into place (an ENT surgeon can do it, though). Second, "lint" cannot get from your ear canal into your inner ear to cause dizziness or balance problems. The fact that your problem cleared up in a couple of weeks means you probably had a viral infection of the inner ear, which gets better on its own without the acrobatics. Based on the information you gave, I would not go back to that "doctor".

I fully concur with the advice to see a (competent) doctor. And if your family doctor seems unsure or says "it's nothing", unless he can give you a specific diagnosis (like a blocked Eustachian tube causing temporary increased pressure in the middle ear), see an ENT surgeon (otolaryngologist). Dizziness (which is a general term for feeling unsteady, lightheaded, or imbalanced) and vertigo (which refers to the specific sensation of spinning, where you feel that your environment is moving around you) are symptoms that have many underlying causes, from a simple cold to a brain tumor. Over-the-counter or folk remedies can be very effective for some of these conditions, but DON'T use them until you know for sure what you are dealing with.

Here's a page from the University of Washington Dept. of Otolaryngology that has lots of useful information.

Aloha,
