Hello,my name is dr,Dorina Gurabardhi. I understand your concern. Most blisters heal on their own. Home treatment may help decrease pain, prevent infection, and help heal large or broken blisters. Some advices that I can give to you are: -Use a loose bandage to protect it. Leave the area over the blister open. -Do not drain a blister of any size if you think your blister is from a contagious disease, such as chickenpox. -If a blister has torn open gently wash the area with clean water. -Watch for a skin infection while your blister is healing -One way to help decrease itching is to keep the itchy area cool and wet -Try a nonprescription medicine to help treat your fever or pain like acetaminophen. Hope my answer was helpful,if you have any other question I will be glad to answer,thanks!
