How to show your symptoms to your doctor

By Petr Nezval, developer of Symp Trac · Updated July 2026 · 4 min read · Not medical advice

The waiting-room ritual of scrolling a notes app while the doctor watches is where good diaries go to waste. Appointments average a few minutes of actual discussion — your diary has to compress into that window.

Bring an overview, not a diary

Doctors don't read diaries; they scan summaries. What works is one page per month: which days were bad, how bad, and what else was true on those days. A month-at-a-glance table or graph answers "how often" and "how severe" — the two questions that drive most treatment decisions.

Lead with the three sentences

Before showing anything, say: how many bad days this month versus last; whether it's trending better or worse; and the one thing that seems to make it worse. That's the frame — the printout or screen is evidence, not the presentation.

Numbers beat adjectives

"It's been terrible" invites a sympathetic nod. "Eleven days at severity 6+, up from six days last month" invites a treatment change. If you track on a 0–10 scale consistently (see how to set up your diary), this sentence writes itself.

What to export

A CSV of your raw entries is useful for specialists who want detail; a one-page PDF summary is what actually gets looked at in the room. In Symp Trac the CSV export is free and the doctor-ready PDF report is part of Premium — either way, arrive with the month already condensed.

Track it in Symp Trac — a private symptom diary for iPhone & Apple Watch. Two-tap logging, a month on one screen, doctor-ready reports. No account, no ads; the core diary is free.
