The following information was reported: INCORRECT ROUTE OF PRODUCT ADMINISTRATION (non-serious) with onset 17Jan2023 at 14:00, outcome "unknown", described as "My left arm subcutaneous"; DIZZINESS (non-serious) with onset 18Jan2023, outcome "unknown", described as "dizzy"; SYNCOPE (medically significant) with onset 18Jan2023, outcome "unknown", described as "fainted"; BLOOD GLUCOSE INCREASED (non-serious) with onset 18Jan2023, outcome "unknown", described as "my blood sugar was 142 and rising / it was at 157"; HYPERHIDROSIS (non-serious) with onset 18Jan2023, outcome "unknown", described as "profuse sweating"; FATIGUE (non-serious) with onset 18Jan2023, outcome "unknown", described as "tired". The patient underwent the following laboratory tests and procedures: Blood glucose: (unspecified date) 115, notes: it is normally like 115; (18Jan2023) 142, notes: my blood sugar was 142 and rising; (18Jan2023) 157, notes: I took it again and it was at 157; Body temperature: (18Jan2023) unknown results, notes: I got up to check my temperature.  Clinical course: She received a Bivalent first dose, yesterday afternoon around 2 pm. She was all fine, she was physically active. Only problem she had was Diabetes (Medical History), when it was tightly controlled, it was normally like 115, so, this morning she woke up, her blood sugar was 142 and rising, this does not happen in the morning. She hardly even had breakfast. So, she got up to check her temperature and took a Tylenol and she started to take her temperature. She fainted between her commode and shower; she could have broken her neck. She did not know how long she was out and then she woke up, see a hole in the thermostat she want to sit there on the commode and that was when she fainted. And then she was tired because she was having profuse sweating. She was sweating like crazy and then she got dizzy and fainted. It looks like fainting was on the list of potential side effect. That was crazy, that was insane. When paraphrased the concern, consumer stated, she got up, she did not see the time, but it was around 5:30 am. But her blood sugar should be below 100 approx. and it was still rising, so she took it again and it was at 157 and she started perspiring profusely, she was sweating, like crazy, like she was at a gym or something then she started getting dizzy, so she fainted. Her blood sugar increased and blood sugar increasing was not only a side effect, fainting was the last side effect but it was just fainting and was associated with the injection of the vaccine. So, she did not faint during injection process, she fainted this morning. There were many as her medicine but she did not even count them.
