i agree, H and T are intertwined. I in fact did not know i had hyperacusis until i took RTG. I just though the pain I was experiencing was simply a part of what tinnitus is. when I took RTG, it sort of isolated and purified the sound, and allowed me to sort of observe it dispassionately with the good mood the drug puts you in, and i think that helped really remove the H. i think H must have some psychological component, but one that is very deep and inscrutable by casual reflection. I was deeply in a state of fear and terror at my T since I got it, and by taking RTG I was able to move past that state of mind.
Just wanted to add another interconnected component to the list: TTS
http://www.hyperacusis.net/hyperacusis/tensor+tympani+syndrome/default.asp
So we have some interconnected syndromes:
-Tinnitus
-Hiperacusis
-TTS
-FEAR, depression, emotional state
In a "healthy" person Tensor Tympany Muscle works of course, but works only in some specific situations
-When someone is exposed to a loud sound: It protects the ear
-When someone is suddently scared, you dont need loud sound to be scared and the muscle can be triggered
When we have T most of times we become in state of constant fear, added to the H, the TTM is triggered so easily. All the area of auditory cortex is hyper activated and a minium stimulous is enought to activate the muscle. I myself reached to point that it triggers just when i touch my face or i shave, you can know it because you listen it, is a strange sound inside your ear(like a pop-unpop). Some people dont know about TTS and think is the same that Hyperacusis, but IMHO its two different thinks, but very related.
When i was on RTG trip it totally disappeared (as fear did), and came a little back when i tapered off.
Now with Keppra im feeling that my H is starting to go away but is still not totally gone, i feel like Keppra works in different way than RTG. while RTG you feel all its power in the first pill you take in 40 minutes, maybe Keppra needs some time to build in.
Now comes my "imaginary" part of this post. Well you know when you have strong pain in a teeth, this pain kind of "expands" the the head, therefore you finally end having head ache.
Well i think with tinnitus happens something similar, the area of the Tinnitus, Hyperacusis and TTS and very close in the brain, so thats why these symtoms are very realted, even you can find people with T and no H and H and no T, but most of us have both. The hyperactivity responisble of T, expands to the areas in the brain causing H and TTS because they're very close. Analogy, T will be teeth pain, and H will be head ache. when the pain starts to go away, first will do the headache and later the teeth, wich was the original cause and stronger one. So I think same will happen when comes to cure T, i think first symptom of curing T is cure the H (and TTS) and later T will be cured. That what most of us experiencied with RTG, we got totally rid of H and partially rid of T.
Apparently, Keppra is more targeted KV channels to a subtype of kv3.1, and not the so-spread KV7 channels of Trobalt. So thats why it erradicated the H without affecting the T while Trobalt affect boths. But i think its a good step to start beating T, because curing H is part of the process even if we dont feel a real change in T volume, its part of the "Tinnitus Pack". Thats why i also think is a good idea to take Trobalt and Keppra together.
