Man, I think this is fantastic news, there are not so many people with burning pain hyperacusis that healed!
I read many of your posts but I did not figure how long did you have the burning pain in your ear(s)?
May I ask if it was constant or if it lasted just for a small period of time after you were exposed to noise?
Thanks and congrats again!
Off-topic a bit maybe, but I actually just had a moderate noise trauma from a set of speakers a couple of hours ago and now I got some dull pain that I hope won't turn into something worse/chronic...
Anyways, when I had my last chronic worsening after a headphone-noise trauma in November 2020, the worst pain lasted for maybe 3-4 months. Or, it's not like it was always there and then suddenly it went away. It comes and goes, then it "goes" more and more, until it was back at some kind of manageable baseline, although not as good as before the accident, but I'd say maybe 70% where I was before.
There was one event though that made me much better over only a couple of days, around March 2021 I think, which was a trip I did to another city to visit family and friends. All I can assume is that the change of scenery, pace and "daily routines" somehow created some new neurological pathways that made my nerves relax or something. When I did the 5 hour drive to go there, I was uncomfortable with the in-car noise, driving by myself even with my over-ear ANC headphones. When driving back a week later, I had a friend in the passenger seat that I talked to the whole way - no headphones, no earplugs, nothing! It was a crazy change and I couldn't believe it.
I discussed this with my therapist and he wasn't surprised by what had happened. He explained that a lot of "pain management" in healthcare uses more or less the same method to alleviate chronic pain in patients - giving the brain "new"/varied input. The pain is real and physical, no doubt, but how the brain and the mind acknowledges the pain (or doesn't) causes the actual experience in pain level to change.
So, to kind of round up what I'm trying to say, and answer your question; My chronic dull/burning pain lasted about 3-4 months at the worst, initial level. My good days then started to get better and more frequent. I'd say that I was back to my current baseline after maybe 7-8 months, but I didn't do a journal or anything, so it's hard to say exactly though. But what I encourage you to do is to try and change up your everyday life and see if that "tricks" your brain into not thinking so much about the pain, because once you stop thinking about it, it will most likely also start to decrease in actual level over time. Go outside, meet some new people, do some new things - with appropriate ear-protection of course, but also without overdoing it. It's a shitty and annoying balancing act, but what choice do we have?
