Pay attention to symptoms that are:
New.
Persistent.
Progressively worsening.
Unexplained.
Repeatedly returning.
Associated with several other symptoms.
Your body can change naturally with age, but persistent changes should not automatically be attributed to getting older.
When Should You See a Doctor?
You don't need to panic every time you notice something unusual.
The majority of skin and nail changes have causes that are not life-threatening.
However, it's reasonable to make an appointment when a change is new, unexplained, persistent, or progressively changing.
A healthcare professional may examine the affected area and, depending on the findings, recommend blood tests, imaging, a dermatology evaluation, or another type of investigation.
For certain symptoms, prompt evaluation is particularly important—for example, rapidly spreading redness with fever, uncontrolled bleeding, severe swelling, difficulty breathing, or other sudden severe symptoms.
Don't Let Social Media Diagnose You
Posts about health often use dramatic language such as “never ignore this” or “your body is warning you.”
