Welcome to Healthcare Magic.
From your query it appears that there is scab/ Crust formation over the wound. It seems to be superficial to upper dermal burn which formed scab on third day. Please stop doing home remedies
for your problem as it can get infected any time. Secondly can form bad scar or keloid if not properly treated. Have you took Tetanus toxoid injection
after it?? or are you properly immunized. If not, then go to a doctor who can give the same and also can give proper antibiotic and dressing to treat the wound properly. Please don't try to pull the scab by yourself as it can definitely be very painful and leave raw area prone for infection.
Get well soon sir,
Dr Sanjay K Kanodia
