If your arm soreness is severe or does not go away after a few days, you should see a doctor.

Why Does My Arm Get Sore After the Flu Shot?

The flu shot is made with inactivated flu viruses. When the flu vaccine is injected into your arm, your body's immune system responds by producing antibodies against the flu viruses. These antibodies help protect you from getting the flu.

The soreness you experience after the flu shot is a sign that your body's immune system is working. The soreness is caused by inflammation, which is a normal part of the immune response.
