What could be the cause of intense itching just on my legs? No rash just itching!

Leg itching. Don't know how long it's been going on. Did you change your soaps or laundry detergent? Are you taking any medication by mouth? Do you have any pets? Does it itch all the time? I would have to know some of these answers. Meanwhile use either dove or cetaphil washes, change your laundry detergent to all free & clear, and apply a hydrocortione cream. If no better, see a dermatologist.
