Four days ago my leg got burnt because of a silencer. It blistered over few hours and the skin completely came off the next day. I applied cold water and burnol over it. I had kept it covered just for one day because I was travelling and I was scared of getting infection but when I removed the cotton it was filled with pus. Since last three days I haven't covered it but it hurts constantly and specially when I'm just standing. The skin around it is reddened and slightly warm to touch. Is there anything I can apply or any medicines I can have that could help? I haven't had any medicines so far and the only thing I have used on it is burnol.
