Additional Information: The patient called about her most recent Covid Vaccination, Corminaty. She had the vaccination on 18Sep2023. She never had any adverse reaction except for tremendous soreness where she can't lift arm without pain along inside of the arm. The pain is not at the injection site. It didn't hurt at the injection site, and it didn't turn red and no fever. Since then, she has had extreme pain on inside of the arm. She is wondering if it is connected. This happened at the same time as getting the injection. It started almost immediately. Initially she thought she was sore from vaccination. Then realized it was not at the injection site and more of the side of the arm and at the shoulder part where she couldn't lift. That concerned her. She mentioned it to her doctor. The doctor said she should not have Flu and Covid shot in the same arm at the same time. She informed that she had asked the pharmacist if that was okay before she had the injection and the pharmacist said yes. The doctor said there could have been nerve damage and that was not reversible. The doctor said she wished she had known because that it is not a good idea to have both vaccinations at the same time, she should have waited a couple of weeks. The patient didn't know, and the pharmacist didn't give that warning. She asked because she tries to keep up on those things. All her vaccinations are current on Covid. This was the latest release, she got it right away in early September with the latest version. She got both flu vaccine and Corminaty in left arm at the same time during the same visit. Flu vaccine: manufacturer, NDC, LOT, and expiry date are unknown.
