Hot shot: A local reaction to the immunization is usually related to the pertussis component treat with Tylenol (acetaminophen) if needed if not improved you should be concerned with a sterile abscess or infection in usually will manifest in a 3 day period . you should have this looked at

Local Reaction: The reaction is may be due the DTaP vaccine. A local reaction with readiness and swelling is common. A cold compress can help. This type of reaction usually occurs at the site of the injection. A reaction below the site may indicate a reaction to something else, perhaps a glove.
