weak; does not feel well; Stomach is upset 24/7; TSH is off; skin so itchy; dry heaves; nauseated/Nausea; sore arm; I don't like the way I'm feeling; This is a spontaneous report from a contactable consumer (the patient). A 76-year-old female patient received the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Lot Number: EW0773) via an unspecified route of administration in left upper arm on 04May2021 11:00 at age of 76-year-old at single dose for COVID-19 immunisation. Doctor wanted her to get it. Caller said that her doctor told her she wouldn't make it if she got COVID. Her heart couldn't pump very well and was very weak. Other medical history included a lot of allergies (They made her sit in a recliner for 30 minutes) and thyroid disorder. No further details provided by the caller regarding her thyroid condition. Caller did not think there were any other medical conditions that she had that would be relevant as she was pretty darn healthy. Family medical history relevant to AE: Not that she knows of. Daughter had the shot and was sick for 2 days. She had the Pfizer. No vaccine administered on same date of the Pfizer suspect. No history of all previous immunization with the Pfizer vaccine considered as suspect. No prior vaccinations (within 4 weeks).  Concomitant medication included levothyroxine sodium (SYNTHROID) taken for thyroid from an unspecified start date for 20 years and ongoing. Got the shot 04May2021. Dry heaves on 04May2021: Didn't really throw up, but she had them all day. Still has them but not as bad. Nausea/ nauseated on 04May2021: It was actually kind of steady. Caller was able to eat and drink, not that she wanted to. She did not know what to do with herself. She was eating and drinking. She took TUMS [CALCIUM CARBONATE] and always had a cast iron stomach. Skin is so itchy on 04May2021: Skin started itching right away, that evening that she got the shot. She even used a back scratcher. It was all over and still felt the same. Treatment: Had taken diphenhydramine hydrochloride (BENADRYL) maybe once or twice and when she went to bed. She didn't take it steady. She did not take the TUMS steady either. Yesterday, she felt better, and currently felt worse again. Had a little more energy and was feeling good. Sore arm on 04May2021: Was sore right away, after the shot. It was still sore but it was better. It was not red or anything. Treatment: Took 1/4 of a paracetamol (TYLENOL), 325mg, so it was 12 or something. Weak on an unspecified date and did not feel well on an unspecified date. Her blood pressure was good and she has no fever. She also stated her stomach was upset 24/7. She didn't like the way she was feeling after the first dose (May2021). She just wish this would go away. She didn't feel good. 10 days was a long time to have a reaction. Tests: Recently had blood work and everything was normal. Even her thyroid stimulating hormone (TSH) which she got tested for every month is fine. It was off but currently was regular. The event did not require a visit to emergency room or physician office. Her next shot was on 25May2021 and was scared to get it. The patient asked what would happen if she did get the second dose. The outcome of events "skin so itchy", "nauseated/nausea" was not recovered, of events "dry heaves", "sore arm" was recovering, of "TSH is off" was recovered, of other events was unknown.
