Clinical course details: The patient reported that she was kind of confused about the whole thing she received the Pfizer COVID-19 Vaccine on Feb2021, and she have been dealing with a lot of different odd things. She had experienced some odd events such as diabetes, migraine, vertigo, severe nausea, and dizziness. She now has diabetes and migraine which she did not before and apparently the third thing which is she guess her main concern is her doctor's saying it could possibly be the vertigo, but it is, so she has such severe nausea and dizziness, sometimes she can't function and it's every day and there is no medication that helps it. She got medications since tried to kind help it and it seemed like helped for may be a couple of hours during day, but it doesn't completely give rid of it. She tried different medications which have not worked. She's been in and out of the hospitals. She had CT scans and X-rays done, and she has done all kinds of different labs. She does not want to blame it on the vaccine, but she's confused. She didn't want to tribute to the vaccine but now that she ruled out absolutely everything out, so she guess it is due to the vaccine. She mentioned some people reported the same side effects as her. She's not feeling better with all the treatment medications she has received from the doctor and the hospital. The doctor is not able help. She inquired if these side effects have been reported with Pfizer COVID-19 vaccine.; Sender's Comments: Based on the temporal relation, the association between the event of Diabetes Mellitus and the suspect product of BNT162B2 cannot be completely ruled out.
