I agree. I'm in benzo withdrawal and I wonder every day why I fight it, when I most probably will be left with the terrible noxacusis anyway. Benzos used to help, but not any more.
I can say that a combination of Baclofen, Oxycontin and Mirtazapine helps somewhat, but it is hardly sustainable. I'm going to try Ambroxol soon as it affects the NaV1,8 and that's pretty close to the NaV1,7 and has similar effect on nociceptive cells.
From WIKI:
Nav1.7, as well as Nav1.3, Nav1.8, and Nav1.9, are the specific channels that have been implicated in pain signaling.
I feel your pain,
@Orions Pain. Noxacusis is one of the worst things that can happen to a human, but with no recognition from the health society. I have to beg on my knees to my doctor to get Oxycontin.
