It's likely that you have a TMJ condition - the jaw not being able to open wide, the clicking sounds, and the perceived deviation. As the eustachian canal is next to the joint, inflammation and some blockage of normal drainage can result, causing the dizziness. There are, of course, other conditions that can cause the dizziness you describe (in conjunction with or separately from the TMJ). (It's allergy season, for one.) There is no substitute for proper diagnos(es), but what you describe is consistent with TMJ. How you have the TMJ treated, however, is a different story - massage therapy of the various jaw muscles is one modality. (In my case, although I have a TMJ condition, massage therapy keeps my jaw muscles reasonably well aligned.) There are various muscle groups that can cause earaches, dizziness and pain (e.g., the deep massater). Janice Travell, M.D.'s two-volume work on muscular trigger points is considered the standard text. Last week, I consulted the TNJ clinic at NYU Dental School in New York - there I met with one of the faculty and a very experienced P/T. There may be a similar teaching hospital in your area. In a couple of weeks, I have an appointment at the headache clinic (dept. of neurology) at a teaching hospital (I have some arthritis and headaches may be migraines and not only muscular-tension type). Also, I had recent root canal and perio problems, shooting pain in that area... Sounds like whatever condition you have is flaring up - a deep cavity (which can be in need of immediate treatment) could be acting up.
Raising six kids is a real balancing act.... (Personally, I find that a hot shower is what gives me most relief from pain - doesn't fix the condition, but make pain and dizziness tolerable.) Good luck. (I'm rarely on the site.)
