Good day is it posdible for a 10 year old to hav smelly, itchy discharge?

Possible in anybody: Anyone can have a discharge. There is usually an over-the-counter treatment option to treat a discharge, as well as a prescription-only option.

A discharge can come from places such as the eye, nose, ear, urethra, vagina, anus, skin wound, etc...
