Infection by shank`s pony?

After using the public showers at my school when i stayed overnight (overnight tour), I reflect i might have gotten an infection on my foot. I forgot to bring sandals, so i walk into the shower barefoot. About two days after I got support, the area around my foot had turned red and i get blisters that popped and stuff it looked really nasty. I thought it be due to too much moisture in my foot so i put some baby powder on it but later two days ago this bump that i thought was a blister turned pale and swelled up like crazy. its really big right in a minute, and so it hurts when i walk. I've be putting neosporin on it, but what can i do to make it walk away? I've never had this condition in the past, and i think it's call athletes foot?Infection by shank`s pony?
Blisters occur as a rule due to increased moisture content in and around your foot,jus try not to puncture or pierce them...
Neosporin would do economically.jus clean youur foot completely n apply neosporin n jus tie a covering around your foot,because thats the only wat to prevent your foot from getting exposed to dust n other foreign bodies...
foot powder or spray
ring worm aka athletes foot the cure comes surrounded by a spray (LOTRIMIN) sold at wallmart for 3.50 to 5.00 in two weeks used twice a morning at least once a daytime will cure it.
