It's not that Dad itches. When he rubs his face or sees a place on the back of his hand he picks at it. It's more picking then scratching. With the extensive sun damage to his skin there are lots of little rough places for him to pick at... and with all the vascular issues and blood thinners over the years he has what they call onion skin. It breaks easily. So he picks at a place and creates a broken place in the skin which scabs over and then he won't leave that alone. When we get one place healed up he creates another one.
Martha, Dad has been to the dermatologist more times than I can remember because of his skin. He has actually had several skin cancers removed. It was the recommendation of the dermatologist to rub his arms and hands down with Vaseline. She said it was the best thing you could use. All I know is that his hands and arms look better when they are rubbed down daily with Vaseline and that is the one thing that keeps him from tearing his skin.
That why I love the medical community so much
