Endometriosis

An endometriosis pain diary that gets taken seriously

Endometriosis pain is routinely underestimated — partly because it's invisible, partly because "how bad is it?" gets asked on a good day. A daily diary converts invisible pain into a dated, numbered record that's hard to wave away.

Daily scores, cycle-aware

Pelvic pain on a 0–10 scale every day — not just bad days, because the zeros are what make the eights credible. Track your cycle phase alongside; endo pain that consistently flares outside menstruation is clinically meaningful information, and only a diary shows it.

The satellite symptoms count

Fatigue, GI symptoms (bloating, painful digestion), pain with specific activities — log the ones relevant to you as separate metrics. Endometriosis is systemic; a pain-only diary undersells what you're carrying, both to you and to the clinic.

Runs and ratios, not memories

After a month you can state the sentence that changes consults: "14 days at pain 5+, of which 8 outside my period, versus 9 such days last month." Compare that to the alternative — "it's been bad" — and you see why the diary exists. Presentation tips live in the appointment guide.

Patterns worth checking

Sleep and stress commonly modulate pain intensity with a delay; the shifted-day comparison from the trigger guide applies here too. And if surgery or a medication change happens, keep the diary running — the before/after months become your personal evidence of whether it helped.

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.

Frequently asked

Why track pain every day and not only flares?

The pain-free days give your bad-day numbers context and credibility — '14 days at 5+' means little without the denominator.

What convinces a gynecologist to act?

Consistent dated pain scores mapped to the cycle, over at least a month or two — especially pain that persists outside menstruation and impacts function.

Should I track through treatment changes?

Absolutely — the diary is the fair before/after judge of whether a treatment, medication or surgery actually moved your months.
