Treatment of Early CRPS with Inflammatory Signs: Edema, Warmth, and Erythema

This protocol addresses the early phase of complex regional pain syndrome — within the first 18 months from onset — when the affected extremity shows prominent active inflammatory signs. Early-phase CRPS may respond differently to treatment than the persistent, longer-duration form of the condition.

Clinical Scenario

Disease duration up to 18 months, with prominent inflammatory signs of the affected extremity:

Edema Warmth Erythema

Early CRPS (up to 6–18 months duration) can respond differently to interventions than persistent CRPS, and this presentation warrants a specific treatment approach.

Treatment Approach — Partial Overview

For this presentation, the protocol involves a short course of oral corticosteroid therapy combined with an interdisciplinary functional restoration program. The full regimen — including sequencing, tapering guidance, and decision criteria — is available in the complete protocol.

Full algorithm and clinical details are in the linked protocol.

Early CRPS (up to 6-18 months duration) can respond differently to interventions than persistent CRPS.

Some evidence (level 2) suggests that very early initiation (after trauma) of steroid treatment (approximately 30 mg/day for 2–12 weeks, followed by a taper) may be effective.

Given the data, a short course of steroids may be indicated in early CRPS with prominent inflammation, but longer courses are unproven and there are numerous, serious contraindications to chronic steroid use.

Many patients may have spontaneous improvement in inflammatory features over time—even those patients whose pain does not get better.
