I was out in the rain wearing socks and sneakers and my right sneaker got soaked completely through. Long story short I ended up walking around in the wet socks/sneakers for a few hours and slept for a few hours with them on as well.
When I finally got home I took my shoes off and my right foot was itchy and swollen on the bottom. It was just a mild bit at the front of the foot, but it's been 2 days now and it seems to be getting worse and spread to the back of my sole as well as in between my toes.
