Additional information: The patient reported that about 3-4 days after her second dose of the Pfizer-Biontech Covid19 vaccine, the adverse events started. She said when she spoke with her ear doctor about the soft patter sound in her ears coming back, her ear doctor was rather flip, and asked her if she would rather have the COVID-19 Virus, or the soft patter sound in her ears. She said the first time she went to her ear doctor, on 15Mar2021, she had her hearing tested, and nothing had changed with her hearing. She said she thought her left ear hearing had changed slightly. She clarified her hearing was very good. She said she had no blood work done with her ear doctor. She said her ear doctor cleaned the wax out of both ears, and checked her ears, nose, and throat. She said the second time she went to her ear doctor (on 07Apr2021), her ear doctor dug out a skin flap in her right ear. She said her ear doctor told her the skin flap in her right ear may have been what caused the soft patter sound she was experiencing in her ears. She said the removal of the skin flap in her right ear did not take care of the soft patter sound in her ears. She clarified her hearing was very good, and nothing had changed with the soft patter sound in her ears. She said the soft patter sound in her ears was no worse, or no better, and was kind of an annoyance. She said her ear doctor was sending her for a sleep study because he thought she snored.
