I recently got a hpv or gardasil shot in my left arm. it has now been two days and symptoms of a reaction have developed. please help!

What kind of reactio: What kind of symptoms? Swollen arm? If so, cool compresses for 20-30 minute intervals will take the swelling down in a day or two?

Local reaction: Reactions at the site of injection occur with some frequency with almost any vaccine. If this continues to enlarge, be red and tender or if you have any symptoms such as fever or chills, see a doctor asap.
