H.e.l.p(again:])a.s.a.p. PLEASE!?

so like 5 hrs. ago i posted a ? about my foot and all the comments said its probably broken. since then,i have taken painkillers and showered and it feels the same.i read only the easiest bone to break (in ur foot) is the top bones called the metatarsals. thats where my foot hurts the most. i have a HUGEEEEE bruise there and its really sensitive. i waas wearing jeans earlier and when the end of the jean just grazed where it hurt, i felt like crying it hurt so bad. when i walk, it only hurts when i reach the pad part of my foot (like right below the toes on the bottm of my foot) ANWAYS my question is how to you tell if the metatarsals. are broken, fractured, sprained, or just bruised? and what would the doctor give me if it was broken/fractured/sprained? thanks yaaa!
