Why Does My Arm Hurt After Flu Shot?

Getting a flu shot is an important way to protect yourself from the flu virus. However, some people experience pain in their arm after getting a flu shot. This pain is usually mild and goes away within a few days. But what causes this pain? And are there any ways to prevent it?

The pain after a flu shot is caused by the body's immune response to the vaccine. When the vaccine is injected into the arm, the body's immune system sends white blood cells to the area to attack the virus. This can cause inflammation and pain.

There are a few things you can do to help prevent pain after a flu shot:

Use a cold compress. Applying a cold compress to the injection site can help reduce inflammation and pain.
Take over-the-counter pain relievers. Acetaminophen or ibuprofen can help relieve pain.
Massage the injection site. Gently massaging the injection site can help improve circulation and reduce pain.

If the pain is severe or does not go away after a few days, you should see a doctor.
