Red bump on leg

LeAnn

Yesterday i noticed this red blotch/bump on my leg. I thought maybe it was just dry skin so i put lotion on it last night after my shower but its still here and looks the same as yesterday.

It doesnt itch, doesnt hurt, and i never noticed it before yesterday. Any ideas as to what it could be?

P.s. i sit criss cross applesauce a lot in school and thats about where my foot/shoe would touch in that position. If this contributes at all.
