Understanding Symptoms
Symptoms are changes in how you feel or function. They can be physical, emotional, or both. Noticing when they began, how they change, and what affects them can help you describe them to a healthcare professional. Symptoms alone don’t always identify a cause, so avoid self-diagnosing.
What to pay attention to
Sensation
What you feel
Describe the symptom in your own words and where you notice it.
Onset
When it started
Note whether it began suddenly or gradually.
Progression
How it changes
Record how often it happens, how long it lasts, and whether it is getting better or worse.
Intensity
How severe it is
Use a simple scale, such as mild, moderate, or severe.
Environment
What affects it
Note possible triggers, activities, foods, medicines, or anything that seems to ease it.
Correlation
Other changes
Include symptoms that happen at the same time and any effect on sleep or daily activities.
When to seek urgent help
Get emergency help for severe or sudden symptoms, such as difficulty breathing, chest pain, fainting, sudden confusion, or signs of a stroke. If you’re unsure how urgently you need care, contact a healthcare professional or local medical advice service.
