Oh, well, where to begin - I had my second Pfizer shot yesterday and within an hour of the shot, my tinnitus (already bad before) became louder, more intrusive, and more difficult to ignore, especially while wearing ear plugs. Last night, I slept very little - started having fever, chills, muscle aches, and fatigue. The tinnitus was at a level that I had never previously experienced and no amount of masking noise or pills could induce me to fall asleep. Today things seem a tad better - it is still louder than it was before the shot, but I also noticed that lying with a migraine patch on my forehead affected it for the better. Perhaps, this bad spike is due to the "stormy" inflammation from the shot and after some weeks, when by body response settles, the tinnitus will settle again to more tolerable levels.
I am sorry that so many others have either experienced a bad spike or the onset of tinnitus/hyperacusis after their first/second shot. I still think that COVID-19 poses more serious risks than the vaccines, but it is discouraging to feel like we have to choose the lesser of two evils.
