Arms

  • Experimental: Pain sensitization parameter testing
    Pre-inclusion visit (routine care consultation): Verification of inclusion and exclusion criteria. Inclusion visit (Day 0): Consent signing, questionnaires (ConvergencePP Score/Central Sensitization Inventory, DN4), and a series of tests, followed by the application of the high-concentration capsaicin patch (PCHC) (performed during routine care). Day 30 visit (±7 days): Questionnaires (same as V1 + PGI-c) and a series of tests.

Primary Outcome Measure

Composite criterion [ Time Frame: Difference between Day 0 and Day 30 ]
