Question: does anyone know of any connection between opioid use and an increase in hyperacusis or tinnitus? I've been taking MS Contin (morphine) for about three months now due to Trigeminal neuralgia and other nerve pain brought on by hyperacusis which had brought me to the brink of suicide, it was that bad. The opioids managed to ramp down the pain just enough to get by, but for the past two months I have noticed that my tinnitus is louder than at any point in the past year, consistently loud, and pulsatile, which I hadn't had since last fall when it first began. Similarly, my sound sensitivity has been inching its way back to levels I haven't seen in a while. Again, there are no other particular incidents I can point to that would increase the T and H. Any thoughts? I found some people talking about opioids and tinnitus, but mostly Vicodin and OxyContin, have not been able to find anything specific about morphine. It would be great to just stop it for a couple days and see if there's a change, but the dosage means that I'm going to be facing a long protracted withdrawal. If it's ototoxic though, I need to know that now.
