I have small lips, so they didn't look very big, but I could feel them/her lips felt swollen and they were tingling; right away my lips became swollen and tingling. I have small lips, so they didn't look very big, but I could feel them/her lips felt swollen and they were tingling; This is a spontaneous report from a contactable consumer (patient) via Medical Information Team.   A 67-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Formulation: Solution for injection, Batch/Lot number was not reported), via an unspecified route of administration on 21Jun2021 (67-year -old at vaccination) as a Dose 1, single for COVID-19 immunization. The patient's medical history included asthma (she had no SOB) diagnosed in her 30's, which was very much under control. Covid-19 infection from 16Apr2021 to unspecified date and she had symptoms of mild fever and tiredness, allergic to penicillin (PCN), spinach strawberries, milk and milk products, she was diagnosed with Thyroid condition in her late 20's, she has had Anemia in her whole life. The patient's concomitant medication(s) included ongoing calcium carbonate (ANTACID); ongoing levothyroxine sodium (SYNTHROID). The patient was not related to any study or programme. The patient stated that, she had her 1st Pfizer Covid dose on 21Jun2021 around 3:45 or 4:00 right away her lips became swollen and tingling.  She had small lips, so they didn't look very big, but she could felt them. She had asthma but wasn't short of breath. That was her symptoms. She had sat there for half an hour and when she saw that she was able to walk on her own she left and went home. Immediately she had to take Benadryl, she doesn't know if she took one or two, but she watched her breathing. She noticed that she had a taste like lead or metal in her mouth. She was not feeling well. She added that she had COVID before and she need to say that she confirmed that this was prior to the COVID vaccine. Those are the main things that she reported previously and then she went through this for the whole week. She kept having to take Benadryl and it helped and her side effects were reduced with the Benadryl use. Also, she had disgusting diarrhea, it was black and horrible. All of her side effects washed away within the second week. The patient stated that, she waited at the pharmacy for 30 min and then took Benedryl. The lip swelling and tingling lasted 10 days. She took Benedryl for a week every day. She stated mild fatigue at the time after the vaccine and now, (21 days later). She also developed a metal/lead taste in her mouth and had black and horrible diarrhea/ for 10 days duration, then her taste came back slowly. All side effects are gone now. She stated that she had "blood work done and showed she have 20 percent coverage from the virus before she got the vaccine." She was not doing the second vaccine unless someone can guarantee her that this won't happen again. She stated that, the nurse who put on her first dose had read recommendations to the reaction she had and it's now 21 days passed on 12Jul2021 and she was told that she could be worse on the 2nd dose due to an allergy, and she shouldn't take 2nd dose. She added that she was tested positive for COVID on 16Apr2020 and that she must have had it between Mar2020 and Apr2020. She happened to go somewhere and her friend who had cancer so she went and did the test and explained to the nurse that she didn't want to take someone else's appointment and she tested positive. She had asthma so she was a candidate that had to be tested and that's how she found out that she had COVID. The week before was when she had the symptoms, but she didn't lose her taste. She just had horrible tiredness, she was very tired, and she had very mild asthma, but she had a pump. Basically, she had symptoms such as a mild fever and tiredness but that was all that she remembers. When she got the COVID vaccine she went and had another test prior to 21Jun2021 and was negative (19Jun2021) and she also did a blood count and had 20 percent only (provided documents). She was very reluctant to take the COVID vaccine. It was weird, she didn't want to do the COVID vaccine but after everything she saw and how people recommended it, she decided to go with Pfizer and it was what it was, it's her body, but she didn't want to do it. She said the swelling lasted more or less a week, maybe a little more. Sometimes she had the taste that came slowly back but she doesn't taste like silver anymore. When she had COVID, what it had affected was her ears, so she had to go to the doctor for that. She was not well. She also had a thyroid condition, and she took a pill for that, but everything was fine except tiredness and maybe some fever. She clarified that this was when she actually had COVID, and the ears really were only affected. The horrible diarrhea began with the COVID vaccine and it ended in about two weeks, that one took longer to go away. She underwent SARS-CoV-2 test and positive for the virus, but she was negative on Sunday (19Jun2021) and had that test done on Saturday and then she had the COVID vaccine on Monday. She does have allergies when she eats certain things, like food allergies, she has a thyroid condition and she had asthma but that was very much under control. She couldn't say anything like if she was allergic to cheese or milk but there was nothing prominent, she could say that the diarrhea came from. She thought that her having a thyroid condition was incredible because she was anemic from birth but that was something that she had dealt with through her whole life. She was given medications, but she pretty much had a normal life, but it came with tiredness and things like that. She stated that she still has had anaemia it to today and she stated that she had to watch what she ate. What she had was anemia with what was called gastric juices and her body doesn't produce enough so she had to watch what she ate. She does take medication, but she was not an everyday freak of medications. She took an antacid, but she can't remember the name of it right now. The only other medication she takes was Synthroid and it was the original but about a month ago she started taking the generic. Everything else that she may take was over the counter. She stated that, her friend's wife had more or less the same reaction and she waited for three months and then got the second dose, and she was fine. She assumed that when received first Covid vaccine that there was protection of 50 percent so wanted to know if it was ok to wait for 3 months before getting the second dose. The outcome of the event was feeling unwell was unknown and the outcome of other events was recovered for swollen lips, tingling on 01Jul2021, fatigue, metal/lead taste in her mouth, black diarrhea on an unspecifieddate.
