Additional information: Reporter was just trying to report one of the possible side effect and she was trying to do this online but for some reasons website would not let her. It just keeps switching, its like just blinking-blinking and it wouldn't let her choose anything. So, that's why reporter called. She wanted to do this in website. Pfizer COVID-19 vaccine and actually specifically she was talking about Pfizer booster which is the same she feel. Consumer confirmed the starting date of events as 17Nov2021. Patient started experiencing a sharp pain in her ovary and in her bladder and the pain was going towards her legs and she had problems walking. So, actually she had to take couple of days off. Patient was a teacher. So, she had to take couple of days off. So, patient can go to emergency room and obviously because of the shortage she was not able to see the doctor right away so she conduct a work again that day. Again, started feeling the same way and went to emergency room on Friday where she spent the whole entire day (Further clarification unknown) and they could not understand what was happening to her and the pain still persisted. Its not as sharp as the first couple of days but she have never experienced anything like that. So, she can tell that its her ovary, its pushing on her bladder. Its on her bladder consistently was in a sharp pain and the pain radiates towards her legs. So, patient keep limping when she walks and on the first day she could not walk at all. Second shot was EN61 I think its 08. It might be 88. She think its 08 (Not clarified) and the date was 02Mar2021. Booster shot was FH8030 number 3, 12Nov2021. Well, that says 8030 and then that says the number like a 3. Patient don't know if its might a 30 (Not clarified). She guess, they just marked that its her third shot. No lab test. They give her some kind of pain killers when she was in the emergency room but it didn't effect her what so ever. So, then they couldn't find the reason. They didn't, she meant they just did some test thus, no medication was given to her. She was prescribed Naproxen which was the Ibuprofen but nothing else. She have never purchased it. So, she can give you the name. Its the same as Ibuprofen because she have a side effect from Naproxen so she never got it. It was ordered but she never got that. She had the flu shot two weeks no, one week before her booster shot. She didn't had her vaccination before my prior vaccinations like her original COVID-19 vaccination but she did had a flu shot 1 week actually 1 week and half before her booster. She just really wanted to make sure that she don't even know if its kind of after the just wanted to do her part and just report things.  Follow-up attempts are completed. No further information is expected.
