Patient stated that She had some side effects with the second dose which went away the next day she went back to her normal self also but not to the extent with the booster. She wanted to know if they have any information with the side effects occurring in stages. On Friday night or the night of the booster she could not sleep at all (29Oct2021). It was like she had been shot up with a pot of coffee or something. She figured that this might be a sleep disorder, she saw that sleeping disorder was listed on a website, had not slept well since the booster, she clarified that the side effects were not all at one time The next day (30Oct2021) she was extremely tired and exhausted and did not feel well. She understood the lymph nodes. It did not get it all at one time. She then had headache on Saturday (on an unspecified date in 2021) for 2 days. Then that subsided and it went into body aches. Her eyes were so tired (on an unspecified date in 2021) but she could not sleep. She just felt awful, kinda blah, icky feeling(on an unspecified date in 2021). She did not think much of it as they said, if you feel icky it means that the body was working to build up antibodies. Yesterday when she woke up, still didn't get to sleep the next night but she got up she felt cold not chills or freezing, just cold (on an unspecified date in 2021). Her body started hurting more and achy (on an unspecified date in 2021). Her stomach was growling and every time she put food in her stomach it would hurt her stomach and want to go up(on an unspecified date in 2021). The patient questioned was it normal for it to occur in stages, she had a sore arm but that was normal with vaccines anyway. If she was going to have side effects, why not at the same time, she was trying to eat because she needed to eat, she just wanted to get clarification, she has a chat with the physician this afternoon (unspecified date), but she wanted to speak to the manufacturer first, she did not had time to do a report, she did not give any information to them yesterday and wanted to be sure before speaking with the physician.
