3 Days Ago I Stabbed My Thumb With Scissors. The

3 days ago I stabbed my thumb with scissors. the blade went in one side and out the other . I have stitches and the top of my thumb is numb, so I guess I severed a nerve. the cut (or stab wound) is at the end of my thumb, level with my nail. I have pain in my palm and a bit in my index finger, is that normal?
