Symptom Diary
Log symptoms, severity and triggers over time.
Overview
The Symptom Diary is for tracking how a recurring symptom behaves over time, when it shows up, how severe it is, what was happening around it, and what seemed to help. Migraines, joint pain, IBS flares, eczema, dizziness, sleep disturbances, mystery rashes, allergy episodes. The combination of date, severity, and trigger fields means you can later filter the history and see, for example, every time joint pain over a six rated coincided with a high-stress week.
For anyone navigating an unclear diagnosis, the diary is what turns a fuzzy clinical conversation into a productive one. Specialists will ask exactly the questions the diary answers, frequency, severity, duration, triggers, what made it better or worse, and a written record will almost always serve you better than memory under the stress of an appointment. For long-term conditions, the diary doubles as a record of whether interventions are actually moving the needle.
How it works
An entry has a date, a symptom name, a severity rating, optional notes about triggers and context, and free-form remarks about what helped. The list view sorts entries reverse-chronologically with severity colour-coded for quick scanning. Filters by symptom name and severity threshold let you slice the history when you need a specialist-ready summary.
Entries live in your browser's local storage. There is no clinical interpretation, no AI diagnosis, and no shared data. The diary is purely a structured way for you to record what you noticed.
Examples
- Logging a migraine episode at severity 8 with triggers "skipped lunch, bright office light" and notes "ibuprofen after onset reduced to 4".
- Tracking an IBS flare at severity 5 with a note about a recent change in diet, useful for a gastroenterology review.
- Recording a recurring afternoon dizziness at severity 3, useful when reviewing blood-pressure medication timing with a GP.
- Building a six-week record of joint pain through an elimination diet, with severity and food-related notes side by side.
FAQ
Is this a diagnostic tool?
No. It is a personal record intended to support conversations with qualified health professionals.
How many symptoms can I track at once?
There is no fixed limit. Many people focus on one or two primary symptoms to keep entries fast and consistent.
Can I export the diary for a specialist?
Yes. The history view copies cleanly as plain text and can be printed.
Is the data private?
Entries are stored in your browser's local storage. Nothing is uploaded.
What severity scale should I use?
A one-to-ten scale is common. Consistency matters more than precision; the trend is what specialists look at.
