I have ring like infections in my pubic area as well as my back, inner thighs, lower belly area, armpits, arms, chest (bra line), knee, ankles and near my shoulder. They get ichy when in contact with soap and water, sweat and almost every time and sometimes they get dry and when I scratch them , dead cells fall off. They are spreading fast. What is possibly the reason or what kind of infection is it? Any medicine recommendation will also be helpful.
