Ditto Ryan Naylor above. I had no idea what tinnitus was until the day I received my 1st Covid vaccine in April of 2021. The night of my vaccination, my head began to ring with a high-pitched piercing noise. It continued for days, and I had no idea what was going on. I went to an audiologist and was diagnosed with tinnitus. This was no coincidence. I have been living with the same noise between my ears ever since. I feel betrayed by my government for pushing the vaccines prior to fully exploring all possible side effects. One would think that the Pfizer composition could be broken down to discover what component or components have caused tinnitus as a side effect in a small population of vaccine recipients. Similarly, with that knowledge, there should be an antidote for whatever triggered the tinnitus caused by the vaccine. It is psychologically traumatic to live with this nonstop 24/7 ringing in my head with the knowledge that there is no cure and there doesn’t seem to be any movement to delve deeper into this side effect.
