Why Tracking Matters

Studies show that up to 85% of diagnoses come from patient history — what you tell your doctor matters more than most tests. But memory is unreliable, especially when you're not feeling well. A symptom diary provides:

The OLDCARTS Method

Healthcare providers are trained to gather symptom information using this framework. Use it to organize your tracking:

📋 OLDCARTS Symptom Framework

OOnset — When did it start? Sudden or gradual?

LLocation — Where exactly is the symptom? Does it radiate?

DDuration — How long does it last? Constant or intermittent?

CCharacteristics — What does it feel like? (sharp, dull, burning, etc.)

AAggravating factors — What makes it worse?

RRelieving factors — What makes it better?

TTiming — Time of day? Relation to activities, meals, sleep?

SSeverity — Rate it 1-10. How does it affect daily activities?

What to Track

📅 Date & Time

Record when each symptom occurs or changes. Note the time of day — many conditions have patterns (morning stiffness, nighttime pain, after-meal symptoms).

📍 Location & Description

Be specific about where symptoms occur. "Headache behind my right eye" is more useful than "headache." Describe quality: sharp, dull, burning, throbbing, pressure, etc.

📊 Severity Scale (1-10)

Use a consistent scale: 1-3 (mild, noticeable but not limiting), 4-6 (moderate, affecting activities), 7-10 (severe, significantly impacting function). Track how this changes over time.

⏱️ Duration & Frequency

How long does each episode last? How often does it occur? "Pain lasting 30 minutes, happening 3-4 times daily" tells more than "frequent pain."

🔗 Triggers & Relief

What were you doing when it started? What makes it worse? What helps? Include foods, activities, positions, medications, stress levels.

💊 Treatments Tried

What medications or remedies have you tried? What doses? Did they help? For how long? Include OTC medications, home remedies, and their effects.

📱 Associated Symptoms

What other symptoms occur at the same time? Headache with nausea? Back pain with leg tingling? These combinations help narrow diagnoses.

Example Symptom Entry

Here's what a good symptom diary entry looks like:

Tracking Tools

Choose what works for you — consistency matters more than format:

📱 Apps

📓 Paper Methods

💡 Pro Tip: Photo Documentation

For visible symptoms (rashes, swelling, wounds), take photos with your phone. Include something for scale, ensure good lighting, and note the date. Photos help show changes over time and are invaluable for dermatological issues.

Preparing for Your Appointment

Make the most of limited appointment time by being prepared:

Before Your Visit

During Your Visit

💡 The "By the Way" Trap

Don't save your most concerning symptom for the end of the visit ("Oh, by the way, I've also been having chest pain..."). Lead with what worries you most. If you have multiple concerns, mention them at the start so your provider can prioritize.

Special Tracking Situations

Chronic Conditions

For ongoing conditions, track trends over weeks/months. Note flares, baseline levels, and what correlates with better or worse periods. This helps optimize treatment.

Migraines & Headaches

Track potential triggers: sleep, stress, foods (caffeine, alcohol, aged cheese, chocolate, MSG), weather changes, menstrual cycle, and medications. Pattern recognition is key to prevention.

Digestive Issues

Keep a food diary alongside symptoms. Note meal timing, contents, and when symptoms occur. This can reveal food intolerances and triggers.

Pain Conditions

Track pain with activity, time of day, weather, sleep quality, and stress. Include functional impact: what can/can't you do because of pain?
