Hi There. For The Past Year And A Half, I

Hi there.

For the past year and a half, I have been having a ear issue. Its not an ear infection (don't think), but inside there is a throbbing, pulsating feeling which seems to be in my ear drum. I do get head aches, which I was thought could just be from stress. Advil doesn't work for me, so I take excedrin probably a couple times a day since this started (its really annoying and want it gone), it does get worse in a pain twinging feeling in the bone below my ear if I do not take nothing. My doctors treated for allergies, natta, went to two (2) ENT specialist, one said nothing and aspirin won't hurt me, and said he saw nothing and can use a steroid, the other saw nothing, but went for a cat scan and nothing showed up either. At this point, I am so fed up. I am having dental issues, but my dentist said it will not be anything with the tooth due to its on the other side of my face and it doesn't cross over. Please help ?
