on leg or foot? if foot you will have the hong kong foot. itchy skin is mostly due to prolong and excessive drying of your skin. it can be easily treated with moisturizer from the OTC. try to apply as often as possible the moisturizer and you will see the difference.

On more serious look....itchy skin is due to the skin disease or the worst case psoriasis. Psoriasis is a very tricky skin disease. it cant be easily treat. the best most effiecient way to treat it is by using a medical graded UV light.
since i didnt see your skin condition, i think it best for you to visit a dr for the condition.
