A member asked:
After my first allergy shot i had a bad reaction. how long will it take for the red blotches and swelling to go away? dr. gave me steroids.

Give it a week: The initial symptoms of itching/swelling should go away fairly quickly - in the first 48 hours. The redness may last for a little while longer. Best of luck!
