Hello, I know this is old, but I was pretty recovered/recovering the last 6 months. Then I got my covid booster on Monday and I went through a whole wave. Coldness, ear pressure a bit, tinnitus flare up, insomnia, just a lot of symptoms I had gotten rid of. Did it go away for you? The only thing I take is a migraine med and I’ve been taking it for two months with no issues so I don’t think that’s it. Thank-you.
