I just swallowed and listened and my right ear crackled so perhaps it hasn't gone away at all (That was an attempt at a joke). It's normal to hear your ears crackle because of eustachian tubes but the crackling right after t is a much different thing. It's more like a squeaky crackle.
I don't remember when the crackling went away or how. All I know is all the symptoms I had when t started have faded except the darned t. I also notice, almost 2 years later, sometimes my ears feel tense or tight. It doesn't concern me but it tells me perhaps there is more healing to come for me. Oh, and sometimes my eardrum flutters, especially in my right ear.
If you find my first post on the site it chronicles my time with t, I assure you I was just as much of a wreck as you two months in and I stayed a wreck for a long time after. I've still got some recovery to go both with my ears and my mind.
I want to stress that if you're patient, really patient because ears take a long time to heal and our minds take a long time to adjust things will improve. Whether the t gets quieter or not you will get more used to hearing it. If you have hyperacusis it calms for most, the crackling will fade, the tightness in your ears will fade. The key is time.
I'm almost 2 years into this thing and still noticing very, very slow progress except with the level of the t. Hang in there, don't do anything drastic and you're going to make it.
