hello, I dislocated my ankle about a month and a half ago, but luckily there was no fracture. When the trauma happened, my foot was slightly cut upon collision , causing the blood to drip out. my foot was popped back in to position, and the cut was stitched (i received 3 stitches). I now feel recovered but when I apply pressure to the cut area, part of my foot feels numb. Is this serious??
