An acute onset of red, painful, hot, swollen, and tender skin, that spreads rapidly.
Fever, malaise, nausea, shivering, and rigors. These may accompany or precede the skin changes.
Unilateral presentation. The leg is the most commonly affected site, and bilateral leg cellulitis is very rare
Examine -
Look for a skin break where the infecting organism may have entered, such as a wound, macerated skin, fungal skin infection, or an ulcer.
There may be diffuse redness or a well-demarcated edge that can be marked with a pen in order to monitor progress.
If the infection is severe, the person may be systemically unwell; tachycardia, hypotension, tachypnoea, or confusion may be present.
Bullae and blisters filled with clear fluid, haemorrhage into blisters, bruising, petechiae, dermal necrosis, lymphadenopathy, and lymphangitis may occur.
