WELCOME TO HCM,
as per the description u have been given , a patch of peeling skin is more pointing towards TENIA PEDIS ..i.e fungal infection
of foot.. and coming to that red bump...it is pointing towards PLANTAR WART
but any how, all the dermatological conditions should be care fully seen directly by an eye, before coming to conclusion..
so i advise you to consult a dermatologist
..and he will take care of it....
