Hi Doctor! I Burned My Foot About 20 Days Ago.

Hi Doctor! I burned my foot about 20 days ago. i dropped some really hot honey over it. it is I guess a 2nd degree burn injury as there was a blister also. i have been using neosprin powder and now started to use silverex. i want to ask that how long will it take to heal .. i have a lot of water activities coming up this month :(. and also will it cause a scar?
