Patient has been diagnosed with tinnitus for around 30 years. Patient reported that the symptom seemed to had increased last night on an unspecified date in Mar2021. She was asking if tinnitus has been reported as a reaction? Yesterday she had her first shot. It was crazy and might not have anything to do with the shot. She has had tinnitus, ringing in the ear, since 1997. Sometimes it just goes up. It went up a little last night. Has Pfizer had any reports of that? They have been doing road work around there so she has been putting ear plugs in and out. Have there been any complaints of tinnitus going up. First Vaccine in March. Side effects were normal. A spike in my tinnitus, gone back done. Reluctant to take the second shout. It was so loud. I think I am going to stick with the one dose. Why? Is it gonna be spike or be temporary? Too nervous it could happen. Is it something to be worried about. Why is it spiking? States that after the first shot of the Covid Vaccine she had a tinnitus spike. States she has been reading that some people have a spike in tinnitus after the vaccine and some of them don't; states there is no rhyme or reason to it. Says that this all occurred back in March 2021. States the tinnitus was frightening, it was so loud in her head.  She could not tune it out, even with her sound machine and was not sleeping on an unspecified date in 2021. States that it has been about 5 weeks and she is back to normal now. She does not think she will get the second shot. She is afraid to go through that again and stated that she does not know why it happened to her or if it may happen again.
