question: I have several bug bites on my legs and feet where some have swelled to the point where you can see a large lump and they also have a large patch of redness around them. Also, 2 bites on the outer part of my left foot have a red rash extending onto the top of my foot and when touched, it feels like a bunch of little needles pricking me. What can I do to reduce swelling, itch and redness?
