Do you have to seek medical treatment for postules?

A "postule" is the idea behind a question.

A "pustule" is an inflamed area that is filled with puss.

Whether or not you need to get medical treatment for a pustule depends on a lot of factors, including where it is on your body, how long it has been there, if it is getting better or worse, etc.

Generally small pustules like pimples do not need medical treatment, but if you have one that is painful or that is beginning do develop streaks coming from it, or is not getting better. Then you need to get that evaluated and treated by a doctor.
