Replace will replace one instance of what you want to replace. Replace All will replace all instances of what you want to replace.

The future tense of "replace" is "will replace" or "shall replace." Example: "I will replace the broken part tomorrow."

Could be eczema, or dermititis or just a skin condition from what you wear or rubbing. There is some creams you can get to put on it such as over the counter cortizone cream with a low dose and apply a thin layer - but of course if your worried have it looked at by a doctor.
