Thanks for using Petco Pet Education Center, formerly Petcoach! This is likely due to an allergic reaction though other things like an infection are still possible. I recommend that you have Mercury evaluated by your veterinarian for further assessment and treatment. They would be able to check for these possibilities and treat accordingly. Allergic reactions are usually treated with anti-histamine drugs and corticosteroids. Good luck!
