I'm still searching for answers Start with the science behind these conditions and the symptoms that tend to travel together. Recognition is the first step toward a name. I was recently diagnosed Get the plain-language glossary, vetted resources and specialist finders, and a place to start building your record. I've been managing this for years Go straight to the Symptom Tracker. Build your Profile, log daily in under five minutes, export physician-ready reports. I'm supporting someone I love Understand what they're living with, and find the organizations and communities that help. I leave appointments feeling unheard Documenting your symptoms for your doctor: a short guide to recording what you're living with so a busy clinician can read the pattern and act on it. I can't explain my brain fog Describing brain fog so your doctor takes you seriously: the words that land in the room, telling fog apart from fatigue, and turning foggy days into a dated record.

The export

Turn your experience into data your doctor can act on

Meet Erin, a sample patient. Her sixty days of logging look like ours: a crash week with no entries, one unexplained bad day, a wedding that was worth the two-day payback. Seen. turns a record like that into a report a busy clinician can read in minutes.

Screenshot of a Seen. daily log: symptoms with severity levels, medications, and activities recorded for one day.

A daily log takes under five minutes, even on the bad days.

Screenshot of the Seen. Medication Timeline chart, with a marker showing the day a medication started.

The Medication Timeline marks when each medication started and what changed after.

Erin is a fictional patient with POTS, HSD, and suspected MCAS. Her sixty days of logging, gaps and all, show what Seen. hands your doctor. Her medications are what she logged, not what I recommend: those decisions belong with your clinician.

The tracker builds this from whatever you manage to log. Perfection not required.
