Diabetic foot infection diagnosis

Not all diabetic foot ulcers are infected. However, infection is often difficult to detect when perfusion and the inflammatory response are limited in the diabetic patient. The common signs and symptoms (i.e., pain, erythema, and edema) of infection may be absent.32 Still, the diagnosis of diabetic foot infection depends mostly on clinical evaluation.
