I'm glad that the CAT Scan showed evidence of the itchiness. Is that the only ear where you are experiencing Tinnitus? If so, I think it's fair to say that the cause in your case has been identified and you can hopefully treat it. Is there anything they can do for the hairs and the malleus?
One thing that ENTs don't like, but I know for a fact works very well, is diluted hydrogen peroxide solution (diluted with warm filtered water -- boil it first, then let it cool down). Insert 5-10 drops into your ear, and then lay there with the water in your ear for 15-20 seconds. Then, tip over and drain out. You will feel a lot of bubbling as the hydrogen peroxide works on your ear wax and the membranes of your outer ear. This routine is used primarily in cleaning ears, but it also has the added benefit of treating the outer ear drum. This may not resolve the underlying problem, but it might cause your ear drum to flex gently and push the hairs out of the way (or perhaps become less sensitive to those hairs). I hope that this might help with your itchiness.
@marqualler - Yes, Advil (ibuprofen) is a fantastic anti-inflammatory. I didn't realize it had a systemic effect, but my maxillofacial surgeon that I went to see last week about my presumed TMJ told me that 3-4 Advil taken three times a day over the course of a week will cause a significant reduction in inflammation. Of course, they don't really want people taking advil at that level for more than 1-2 weeks tops -- the same with prednisone, which has a typical 5- 7- or 10-day treatment regimen. But for these acute cases, this anti-inflammatory treatment can be incredibly useful. If you are concerned about reactions to Advil, there are herbal remedies (some of which
@engineerLA recommends in his various threads) to help reduce inflammation considerably. I haven't used any of them so I can't speak to their efficacy, but I can say that Advil seems to be helping me -- but only at this higher dose. I usually have limited myself to 1 or 2 Advil in the past when I've had a headache or teeth ache associated with braces in my childhood), but apparently breaking the 600 mg barrier allows a saturation of ibuprofen to reach the bloodstream and work on the entire body more intently.
Let me know how it goes. Good luck to you!
