On Saturday 02Jul2022, she went to Urgent care, and they tested her urine and it was clear. They also sent it off for cultures and it came back negative for bacteria. She still had this pain and it felt like inflammation. She thought maybe it was a urinary tract infection because her urine felt warm when it was coming out and the pain she had in her lower abdominal area. Her abdominal symptoms continued through the weekend. The lady from Urgent care referred her to her Primary care physician. She called her urologist and they wanted her to repeat the urine culture. They decided to treat her like she had bacteria in her urine and put her on antibiotics. The culture again came back negative, and she stopped the antibiotics. She had fatigue that was like malaise. Her fever registered as high as 101.5. Since then, it had been up and down and was mostly low grade like 99.3, and yesterday was 100.3. A few minutes ago, it was 98.2 and that was higher than her normal temperature. She usually runs like 97.4-97.5. Right now, it was 98.4. Earlier this morning it was 99.2. She felt like this must be her immune system reacting. This was her second booster. She still feels the pain, but it was not as severe as it was. It did get worse before it got better though. Her heartbeat was worse on Friday and Saturday. She called her cardiologist to see if she could go to the hospital. She stated that she felt a little weird, but not to where she needs to treat the nausea. She felt her stomach was a little weird. She thought that since she had nausea, 2-3 days later she started having bad diarrhea and thinks she lost so many electrolytes, she felt like kind of weird. She was not treating the nausea anymore. She took something on Saturday. After she treated the nausea, she felt better going into Sunday and did not take anything else. She said she took Zofran for the nausea. Diarrhea was like water yesterday 10Jul2022 and was really bad. It had improved as of Today 11Jul2022. She was making herself a electrolyte concoction. She wears glasses. Having difficulty reading her vaccination card. She said that the handwriting was hard to read. When she tried to call the clinic where she received her 3rd dose to let them know what was happening, they never called her back. They only wrote the lot number and the date on her vaccination card. No additional Vaccines Administered on Same Date of the Pfizer Suspect. AE(s) required a visit to Physician office and did not require emergency room. Thought she needed to go to the hospital from the rapid heartbeat and palpitations, but by the time she got a call from her doctor she was feeling better and did not need to go to the emergency room. She had already been to Urgent care by that time. She wanted to find out it was unusual for someone to experience symptoms 4-5 days after the injection. Initially she felt a sore arm then nothing, then the fever came. Is it possible or was she making this up in her head? Is she the only one?
