Cellulitis of the lower limb. Many cases of cellulitis do not require surgery unless necrosis has set in, when the patient needs debridement, or then there is a compartment syndrome(Swelling in the leg which is not settling with conservative means leading to gangrene etc), when a fasciotomy may be needed. This and similar cases are usually treated with medicines and other supportive therapy to heal the wounds. The patient however usually needs to be admitted for a few days to undergo the treatment. After this is done and the cellulitis has settled down, we usually investigate to know the cause, especially in cases of recurrent cellulitis and might suggest a surgery or medicine or supportive treatment to try and prevent future recurrences.
