How to keep a symptom diary your doctor will actually use

Doctors see you for a few minutes; your symptoms happen every day in between. A good symptom diary bridges that gap – but only if it's consistent and easy to read.

What to record each time

Date and time; what you felt and where; severity on a consistent 0–10 scale; how long it lasted; what you were doing beforehand; what you took or tried and whether it helped.

How often

Log when symptoms happen (events like seizures, asthma attacks or flares) plus a quick daily check-in on good days too – good days are data.

Keep it consistent

Use the same scale and the same words each time; note medication changes on the day they happen.

Turn it into something your doctor can use

Bring a one-page summary rather than weeks of raw notes – how many episodes, how severe on average, what changed, and your top two or three questions.

Paper, notes app or tracker app?

Paper works if you stick with it. A tracker app adds reminders, keeps everything dated and can export a report. WellNest does this for chronic pain, CRPS, asthma and epilepsy.
