I am so sorry to hear that, just terrible. "H" stands for hearing? Moderna was a lot stronger than Phizer. Wonder why it has not calmed down a bit.. I really hope that it eventually settles down and improves for you. I am having a T flare up right now and know how distressing it can be. Did you refrain from a booster then? Seems understandable to hold off.

Have you know others that experienced this? Seems like a lot of adverse side effects came about more after second shot for people?

I also have an auto immune skin condition and worry about further activating that too.

Tinnitus and other hearing loss issues are being studied by the World Health Organization. Below is a link to a recent publication on this topic.
