You like to know what causes itchy legs for someone diagnosed with diabetes.

Itchiness is an irritating sensation on the body that provokes a desire to scratch the skin. According to the major symptom that you describe (itchy skin) it is likely that your mother might be experiencing a fungal infection on her feet and legs. Fungal infections of the feet and legs present as itchy red spots on the skin. The changes of the skin during a fungal infection may be different in shape and size, from rounded to undefined shapes, from berry-sized to coin-sized or larger sizes. The changes on the skin may be a few millimeters elevated from the healthy skin. Also the skin that is nearly to the borders of the change may peel off in small particles such as in dandruff in the hair.

I am not able to make a complete diagnosis online for your mother’s medical condition. Please contact your mother’s doctor or a qualified healthcare provider such as a dermatologist for a visual physical exam as well as further diagnosis and treatment options.
