If my theory is correct (and it is just a theory, I'm not suggesting anyone be a Guinea Pig), I think you would benefit more from something like the Flomax referenced in this thread.
I also think (again if my theory is correct) that people who get some relief of pain from benzos might also get benefit from a smooth muscle relaxer (alpha 1 antagonist like Flomax). I don't know its other effects, though. I haven't looked into it enough.
I started getting more mild thumps on both sides and moderate face pain as of two days ago. It definitely seems to be more TTTS in how it feels than true intracochlear noxacusis. If it gets worse, I might be the Guinea Pig (I have access to a similar drug, Prazosin).
