It's been 1 week, I have got this burnt in my right leg ankle by touching a very hot bike silencer. Whenever I walk for going to washroom and all,the skin stretches and because of that some times little drops of blood come from it. Now it's having blackish formed in little parts of the wound but pus is coming sometimes. I am applying coconut oil on it every 3 hours and taking vitamin c chewable tablets. When I apply some burnheal on it it becomes bubbly bubbly so I have stopped putting it since 2 days.
