Thoracic Outlet. Arm symptoms, and what sets them off.
TOS sends numbness, tingling and weakness down the arm — often worse with arms overhead. Leo's TOS hub is a focused dashboard over your symptom logs — it counts arm and hand symptoms and overhead-activity triggers, alongside relevant labs.
A curated view over what you already log.
There's no separate TOS data-entry app. You log symptoms — and tag triggers like arms-overhead — and the hub reads them back: how often arm and hand symptoms showed up, and how often overhead activity triggered them, over the last 30 days.
Physical-therapy work lives in your Workouts, and the hub points you there rather than duplicating it. An optional duration tracker counts the days since onset.
The signals that matter for TOS.
Overhead triggers
Symptom logs tagged with overhead activity, counted over the last 30 days — the classic TOS provocateur.
Arm + hand symptoms
Numbness, tingling and weakness in the arm or hand, counted over the last 30 days.
Symptoms & flares
A 9-symptom TOS set plus flare logging — color change, swelling, neck/shoulder pain, cold hand.
Labs
CBC, CMP and inflammatory come pinned, with trends and reference ranges.
What ships in the Thoracic Outlet Syndrome hub.
Leo tracks. It doesn't diagnose.
TOS is diagnosed by a clinician with exam, imaging and nerve studies — Leo has no screener and makes no claim about whether you have it.
This hub is a focused dashboard over your own logs and labs. Everything is descriptive and on-device-first; the counts describe what you recorded, never predict or advise.
Arm symptoms and triggers, on the record.
A focused dashboard that surfaces arm/hand symptoms and overhead-activity triggers from your symptom logs, with relevant labs and a link to your PT in Workouts — organized for your specialist.
