Why does my arm hurt after i get a flu shot? it feels sore.

Inflammation: Your arm hurts because the injection itself or the flu vaccine injected has produced a low grade inflammatory response and this causes pain. It will pass uneventfully. If it continues or worsens go back and see a doctor.

Expected: Often people will experience soreness in the arm that received the flu shot as the body responds to the foreign material and this is normal as long as it doesn't last for more than a week.
