Good advice is not always a medicine. Sometimes it is a referral.
Online information cannot fully assess a person.
Seek professional help promptly when a problem seems serious or unusual, worsens quickly, persists despite reasonable measures already taken, causes a marked decline in general condition, concerns a particularly vulnerable person, or when you have serious doubt about what to do.
In a potentially urgent situation, do not delay appropriate care while waiting for an online reply or searching for a self-medication solution.
When there is significant doubt, seeking help early is often preferable to waiting.
