I knew that would get your attention.
Well, my kids, especially Ollie swell up a lot if they get a bug bite, spider, fly ect.
My mom mentioned to me that when they get fly bites in Canade ( they go fishing there) that they put Preparation h on their bites and it takes the swelling away.
Well, even though I was a little skeptial, I got some and tried it. Guess what? It works. The swelling goes doen in a relativity quick amount of time.
So I am just throwing that out there to you....
