How to Track Symptoms & Flares Effectively

How to Track Symptoms & Flares Effectively

What gets measured gets managed. Systematic symptom tracking transforms your relationship with your disease — and makes every clinical appointment more productive.

Why Tracking Matters

Without systematic tracking, it's easy to miss patterns that reveal triggers or trends, underreport symptoms to your neurologist, fail to distinguish a true relapse from a pseudorelapse, and miss the window for early relapse treatment. A simple, consistent tracking system solves all of these problems.

What to Track

Core Daily Metrics

  • Overall fatigue level — 0–10 scale
  • Cognitive function — subjective rating of mental clarity
  • Mood — brief rating of depression/anxiety level
  • Sleep quality — hours and quality rating
  • Pain level — 0–10, with location noted
  • Mobility — any changes in walking, balance, or coordination

Symptom-Specific Tracking

  • Vision changes (blurring, double vision, pain with eye movement)
  • Sensory changes (numbness, tingling, burning)
  • Spasticity and muscle stiffness
  • Bladder urgency or accidents
  • Heat sensitivity episodes
  • Word-finding difficulties or cognitive slowing

Potential Triggers

  • Heat exposure (weather, exercise, hot showers)
  • Stress level and significant stressors
  • Sleep quality the night before
  • Exercise type and duration
  • Illness or infection (even mild)
  • Menstrual cycle phase (hormonal fluctuations affect MS symptoms)

Distinguishing a Relapse from a Pseudorelapse

True Relapse Pseudorelapse
Definition New or worsening neurological symptoms lasting >24 hours, not explained by fever or infection Temporary worsening of existing symptoms due to heat, infection, fatigue, or stress
Duration Days to weeks Hours to days; resolves when trigger is removed
New symptoms? Often yes No — existing symptoms worsen
MRI changes May show new active lesion No new lesion activity
Treatment May require corticosteroids Treat the trigger (cool down, treat infection, rest)

Rule of thumb: If you have a fever, infection, or have been overheated — treat that first and see if symptoms resolve within 24–48 hours before contacting your neurologist about a possible relapse.

Tracking Tools

Digital Apps

  • MS Register (National MS Society) — comprehensive MS-specific tracking
  • Flaredown — symptom and trigger tracking with pattern analysis
  • Bearable — highly customizable health tracking app
  • Symple — symptom diary with export function for clinical appointments

Simple Paper System

If apps feel overwhelming, a simple notebook works. Record daily: fatigue (0–10), pain (0–10), mood (0–10), notable symptoms, potential triggers, and medications taken. Consistency matters more than complexity.

How to Use Your Tracking Data

Before Appointments

  • Review the past 3 months of data
  • Identify any new symptoms, patterns, or trends
  • Note the date, duration, and severity of any possible relapses
  • Bring a printed or digital summary

During Appointments

Share specific data rather than general impressions: "My fatigue has averaged 7/10 for the past 6 weeks, up from 4/10 before that" is far more useful than "I've been really tired."

For Insurance & Disability Documentation

Consistent tracking creates a longitudinal record invaluable for disability insurance claims, workplace accommodation requests, and legal documentation.

Tracking a Suspected Relapse — Step by Step

  1. Note the exact date and time symptoms began
  2. Describe symptoms precisely — location, character, severity (0–10)
  3. Check for triggers — fever, infection, heat exposure, extreme stress
  4. Monitor for 24 hours — if symptoms persist without a clear trigger, contact your neurologist
  5. Document daily until symptoms resolve or you've spoken with your care team
  6. Note recovery — partial or complete, and timeline
