She reported as she received her first shot. Clarified as the covid vaccine. She actually has a lot of questions and wanted to report some things. She has a complicated medical history and questioned if she should even get the covid vaccine. She went back and forth with multiple doctors and could not get a clear answer if she should get the covid vaccine or not. She finally just said forget it and decided that she was going to get the vaccine. She got the first dose of the covid vaccine on 04Mar2021. She has gained some weight since covid vaccine. She has been working from home. The weight gain is not because of the covid vaccine, but there has been some weight gain since the covid vaccine, she feels like its inflammation. She has gained 6 pounds. She woke up the very next morning after the covid vaccine and she was swollen, and her face was swollen. She weights herself daily. When she weighed herself this morning, she was 2 pounds heavier. Face swelling has been worse the last 2 days. She has not been 160 pounds in years, she means years. The only reason she was 160 pounds before is because she was on steroids and it made her gain weight. Her weight fluctuated back and forth, a pound here and there. Unknown NDC/LOT/EXP. She does not have it; this was back in 2007. She was really sick going from hospital to hospital in the past, and they were ruling out Addison's Disease, Angioedema, Mast Cell Disease, and carcinoids and she did not end up having any of these diagnoses. She does not have any more information but states that why she was on steroids. No further information provided. She thinks her eating habits haven't changed at all and that's why she concerned about that. The swelling is worse today, yesterday was a bad day. The swelling has come and gone. Today is the worse it has been. She has been taking photos so that she could compare pictures every day. About one hour after receiving the covid vaccine, she experienced tachycardia. It has happened a couple of other times since then, it has gotten better. She has postural orthostatic tachycardia syndrome and also has autonomic neuropathy as part of her chronic illness. Her symptoms go hand in hand with her diseases. Tachycardia is part of her disease and she takes metoprolol for it. When the tachycardia first happened, she had to take an extra metoprolol. She normally only takes one in the morning and one in the afternoon. She never has to take an extra one, but she did take an extra metoprolol that day to stop the tachycardia. Her dose of metoprolol was half tablet twice a day but that was too strong for her and adjusted her dose to one fourth of a tablet twice a day. She did have side effects after the covid vaccine, and she thought they were more severe than others from talking to her friends and family. She had arm soreness and could not lift her arm for several days. She broke her shoulder on 01Nov2020, and they gave her the covid vaccine in that same arm. Her arm soreness started that evening she received the shot and lasted for several days but is now completely resolved. It resolved probably around the evening of 06Mar2021 or the morning of 07Mar2021. She does not know exactly. She was extremely tired the next day, 05Mar2021 after the covid vaccine. This has been ongoing for quite some time. This is what is so hard for her to distinguish because her chronic diseases cause extreme fatigue. She thinks that the vaccine made her fatigue worse, and that was another reason why she was questioning to get the vaccine. She was diagnosed at clinic with her chronic diseases. She was told to not ever get the flu vaccine because they think it is what caused her postural orthostatic tachycardia syndrome. She only took the flu vaccine once in her life and ended up bed ridden once that was done. She was sick the week she got the flu shot and she was never the same. Unknown NDC/LOT/EXP for flu vaccine. She does not know any information about the flu vaccine and no other details provided. States that her tiredness has gotten better as far as the vaccine goes, her tiredness now is because of her postural orthostatic tachycardia syndrome. She had a bad headache. Reports a slight headache started the evening of 04Mar2021. It has resolved but it took a very long time too. She would say that it lasted a good week. She had chills that started on 05Mar2021. The chills have resolved, chills only lasted her a couple of days. She felt nauseous that started on 05Mar2021. She is still feeling nauseous. She has been taking Phenergan and Zofran as needed. She has that symptom, nausea, with her postural orthostatic tachycardia syndrome as well, but she says nausea got a lot worse after the covid vaccine. All she sees on her patient record card is EN number. Clarifies as EN6206. Does not see an EXP or NDC. States that her card says first dose covid 19 vaccine. Clarifies that lot number is EN6206. She is providing her medications, medical history or relevant testing will help our medical information team help her figure this out. She has called an immunologist for help. She has always been an advocate for herself. No one has been able to tell her ingredients of the vaccine. She looked it up online and knows what some ingredients are, but she is not able to decipher what some things mean. She knows what potassium is, but whenever it says lipids she does not know. She considers herself an intelligent person and she has done a lot of research, but she is unable to figure this out. States that this is a joke and is frustrated at how hard it is to get answers. She works in an education in a college setting where she works with people who cannot read, and she cannot imagine how hard it must be for people like them. Clarifies that she is a counsellor in higher education. The immunologist she called was not able to help her, so she called today to talk to people who know more and can help her. She even called her pharmacist to have them help her break this down and they could not help her, she thought it was pathetic. She thinks that providing her medications, medical history and relevant testing is a waste of time for both of us if the people at medical information cannot see the report with everything already listed to help her make decisions. She is asking number one, if she can even take the second dose because of her face swelling. Number two, if it is even safe for her, she wants it but is not sure if she can have it. Number three, how can she get rid of this face swelling. She has had severe allergies to medications in the past. She told them before getting the vaccine. She has had reactions to the extent of anaphylactic shock and had to be treated for it. The patient underwent lab tests and procedures which included weight: gained on 05Mar2021.
