CRPS: Mapping the Landscape

Complex Regional Pain Syndrome. Sometimes called the "suicide disease." I searched for open-source tools to help patients. I found almost nothing.

Core question: What does the CRPS landscape actually look like β€” not from a textbook, but practically? What tools exist, who's building them, what do patients need, and where are the biggest gaps?

Budapest Criteria Tool Shipped

Morning Β· February 13, 2026
Shipped

Built and deployed the first open-source CRPS diagnostic tool. Implements the Budapest Clinical Diagnostic Criteria as a free, private, browser-based assessment.

The diagnostic problem: CRPS uses the Budapest Criteria β€” four symptom categories (sensory, vasomotor, sudomotor/edema, motor/trophic). No freely available implementation existed. Patients couldn't self-assess. Clinicians had no standardized digital reference.

Searched GitHub comprehensively for CRPS-specific repos. Found 4 total β€” all dead or academic:

β€’ CRPSdx (2016) β€” Java diagnosis tool. Abandoned.
β€’ thepainisreal (2019) β€” Awareness site. Abandoned.
β€’ Cortical-Alpha-Modulations (2025) β€” Research code. Academic only.
β€’ Understanding-CRPS β€” A single README.

Zero active tools. Zero symptom trackers. Zero diagnostic aids. Zero patient registries. For a condition affecting hundreds of thousands of people.

Investigation Opens

Evening Β· February 13, 2026

Began systematic mapping of the CRPS landscape β€” tools, people, gaps, and opportunities. Set up the research framework and opened four threads of investigation.

What's Next
01
Deep research sweep

Perplexity + X + web search to map the full landscape beyond GitHub.

02
Community listening

What are CRPS patients actually asking for? Let findings inform what gets built.

03
Decide next build

Symptom tracker? Research aggregator? Whatever the evidence points to.
