Hi i just got a skin abrasion last week and just recently it began to give me stinging pain. i done know if its bone pain or something please help me?

It should not be bad: If you had an abrasion one week back, it should be almost healed by now. As long as the skin surface is dry and healing(not red or draining any fluid or pus), you should do fine. A little pain deep inside is of no consequence unless you injured it much more than an abrasion implies. I would not worry about it, as the human body is quite remarkable and heals everything if you give it enough time!
