I think the same thing happened to me this morning. I just can't help but think it's the silicone earplugs. When my tinnitus first occurred a few years ago, it was a morning after I had been wearing foam earplugs and I had slept on them funny. When I woke up there was a distinct soreness in one ear. And the terribly loud tinnitus began then. Today I've been completely out of sorts and terrified that the same thing has happened again, this time with silicone ones. Even though I have worn silicone ones many times in the past without incident.
The other possibility for today's increased bout of tinnitus is that I started an SSRI about a week ago and it has admittedly been creating with pretty strange effects on my body, namely large amounts of energy.
Anyway, today was very rough. I have a neighbor who moved in above me and I really need earplugs to get through the nights, because he runs a fan that vibrates through the ceiling and is damned distracting.
I read the other posts in this thread, where one fellow suggests that this can cause a barotrauma that, in his example, took a month for him to heal.
If this will heal... I can endure it. If it heals... OK. Then it's just a thing to endure for a month or something.
