I got home night before last and my foot was itching really bad between and around my piggy toe. At work yesterday my foot started to hurt and continued itching. Took off my shoe and noticed a wound looking like a small blood blister right between my two toes. Woke up this morning at 2 am and can't sleep foot is red and swollen and hurts to walk on. Tried to spread toes to look at small blister now foot is hurting really bad. What do you think is happening to my poor little foot?
