Scope
The Bottom Line
- Cellulitis is an acute spreading infection that usually produces a warm, tender, erythematous area and may follow a break in the skin.
- Record extent, pain, systemic symptoms and possible portal of entry and consider mimics such as venous inflammation, gout and DVT.
- Marking the edge can help document spread, while elevation and management of skin breaks support recovery.
- Select oral or intravenous antimicrobial care from the current local policy after assessing severity, allergy and comorbidity.
Practical clinical workflow
Safety boundaries and escalation
- Rapid progression, pain out of proportion, crepitus, bullae, shock or systemic toxicity requires immediate emergency assessment for deep or necrotising infection.
- Orbital or periorbital involvement requires the separate urgent eye pathway rather than routine limb-cellulitis management.
