It's confusing to her but they keep changing the name. She just knows it hurts like heck .Clarified she is reporting about her third dose, COVID-19 Vaccine. The lady who administered her booster dose, wouldn't give caller her name, it made her uncomfortable. She went with her family members and the nurse did theirs. The nurse that did her family member, he is fine. He doesn't have this and his is great. No further details provided.Has been keeping up per the CDC and this new variant. Trying to do the right thing. She has doubts. The myths are just horrible. Has high regards to Dr. and medical staff. Prayed to God that this is being used for the right thing. Got it to be whole and healthy and do the right thing at the right time. Was taking a baby Aspirin, but quit taking it the same day as the booster dose COVID-19 Vaccine or the next day. NDC/LOT/EXP for baby Aspirin not probed over call. The lady administering caller's COVID-19 vaccine booster dose was acting and looking a certain way. She wouldn't give caller her name, only stating they call her. Caller states this is an important shot and the administering person was acting weird. The patient visited neither Emergency Room nor Physician Office.States when she first started getting the Flu shot, she would swell up. Told this to the nurse and it was put in her chart. The nurse stated it would be necessary to warm up the spot first before injection. Clarified the swelling was specific to the injection site of the Flu vaccine. Has had swelling and redness at injection site of COVID-19 vaccine. Was advised by a Pharmacist to take 2 Benadryl. It has continued for 4 days and caller feels it is worse. It is now starting to itch.
