I'm sorry for "spamming" by writing in an old thread such as this, but I'm using it to keep track of my own spike(s), hoping that it will be helpful to myself, should this spike pass and another one come in the future. However, feel free to comment. Any support is good.
Four weeks ago I went to a musical (Book of Mormon), and I did wear my earphones. During the musical I realised that it was louder than I thought it would be, so during the intermission I changed filters (From ACS Pro15 to ACS Pro26). Worrying that I had damaged my ears that evening caused a slight spike, but I believe it had faded a few days later (can't remember exactly, since the current spike is way worse).
Then, 11 days ago, I attended a very loud birthday party. It was held in a nightclub with dinner and then... a DJ. Sound was at what i think is regular nightclub volume, loud. I wore earplugs the entire night, even during dinner, though there was no more music than some in the background. Just a lot of people talking. At dinner I used my lowest filter (Pro15) and the rest of the night my Pro26. (15 years ago, I used to go out all the time to nightclubs, despite my T, always using my "Earfoon" ear plugs. I never ever spiked).
When the night was through, my ears were ringing like hell. I'm guessing this was from the exposure to loud music, but also from drinking quite a lot of alcohol. I've had my head ringing like this before, from just the alcohol and no loud music, so that didn't actually bother me that much, since I knew I'd been wearing my earplugs all night. I do remember thinking at the club something like "how do people without earplugs manage?". Once during the night I measured the sound with an app in my phone. I don't know how accurate it is, I'm a little sceptical, but it showed volumes maxing at around 89 dB, which with earplugs in, shouldn't (?) have been too loud).
Anyway, here I am, 11 days later and spiking. Both my ears seem to be spiking, but at night it seems concentrated to my left ear, which has always been my worst ear. Short periods of time during the day it seems to get slightly better, but it keeps coming back, being louder than the TV and being present pretty much all the time. I hear it when I drive, despite having the radio on and at times it feels like I have a siren inside my head. Anxiety strikes a little at times, but I'm battling it slightly better than the last bad spike three or four years ago. (I think being off work this week is doing more bad than good, also).
I also had the flu four days last week, but the spike had begun before that.
