Hi and welcome, wife. The onset of my disease is recent and so far it is mild. I do have itching on my legs, though. Three times I've had cellulitis, and it was between the ankles and the knees. The first two times it got blisters that "wept" lymph. It was intensely itchy and sore at the same time. I don't know whether that is at all related to diabetes, but if it persists, and especially if it gets worse, I'd tell him to see the doctor ASAP. Hope it's not that, and there are any number of things it could be. Someone more knowledgeable should be along to respond soon.
Take care. Loishttp://www.geocities.com/eljay1066/Aunt_Babe_s_House.html
