Flu shot injection error?

Patient: Flu shot received on Thursday. I was expecting the usual soreness in my arm the next day, but there was absolutely no soreness the following day or even the next. Is it possible the pharmacist did not inject it correctly? I remember commenting to her when she was done that I didn’t feel a thing! Not even a pinch! I chalked it up to her being a great injector, but since I haven’t had any soreness in my arm muscle at all in the following days, I’m wondering if it was done incorrectly. All other flu shots I’ve rec’d produced soreness for a day or two, so this is why I’m concerned about this one not producing any soreness.Thank you,Lee

Symptoms: No symptoms. That’s the concern.
