Suggest Treatment For Itching Of Lower Legs

Hi Doctor,It's been four days since my lower legs have been itching me. I started noticing this on Wednesday and I thought it must have been because my legs were irritated by the socks I was wearing (new and probably tighter than my older socks). But the itch has persisted to the point that I wake up in the night and find myself scratching. Is there such a thing as socks allergy?
