Since last week I have been experiencing severe itching that started on the palms of my hands, then moved to my feet, then my legs (but only below the knee), then my entire legs. Now it's back to my feet again but last night it was my back. At first I was attributing it to dry skin and stared smothering myself in lotion... no help. Then I thought maybe it was just when I went from being outside in the cold to inside where it's warm...the temperature change. That seems to trigger it most of the time, but there are also times when it happens for no reason. There is no rash that I can see, just redness from me scratching it. It is completely impossible to ignore it and not scratch it. It's so severe that it literally makes me flinch sometimes. What in the world could it be? I haven't changed my soap, my shampoo, or my laundry detergent. I haven't taken any new medicine, except for a pain killer prescribed by my dentist for some major fillings done the week before last. I haven't taken one since early last week though. Other than that I can't imagine what it is, but it's driving me crazy... somebody please help!
