Getting a flu shot is an important way to protect yourself from the flu. But one common side effect of the flu shot is arm soreness. If you're wondering how long your arm will be sore after a flu shot, here's what you need to know.

Most people experience some arm soreness after a flu shot. The soreness is usually mild and goes away within a few days. The soreness is caused by the body's immune system responding to the vaccine.

There are a few things you can do to help reduce the soreness after a flu shot:

Apply a cold compress to the injection site.
Take over-the-counter pain medication, such as ibuprofen or acetaminophen.
