One place for a many-sided condition

EDS can involve joints, skin, digestion, dizziness and fatigue all at once, and the pieces often get discussed in separate appointments. A single record puts them side by side.

In Heylixir you log each symptom with intensity and a note, plus your meds, mood and journal.

Explain it with more than words

It is hard to describe a condition with so many parts. A summary of your symptoms, flares and meds over time gives your care team something concrete to work from.

If you also deal with dizziness or a racing heart, see our [dizziness and heart-rate tracking](/dizziness-heart-rate-tracking/) and [POTS](/for-pots/) pages.

Log a bad EDS day with your voice

When your joints are sore, typing is hard. Say what is going on in Heylixir and your voice note logs it for you.

“Shoulder subluxed this morning, sore all over, dizzy when I stood, took my meds and rested.”

Mood: frustrated, tired

Symptoms: joint pain, dizziness, fatigue

Medication: taken, noted with the time

Journal: your words, saved as today's entry
