Welcome to Healthcare Magic Forum
You had developed Viral warts
upon which you did chemical cautery by yourself...
Firstly, i would like to tell you that although chemical cautery is the most commonly used modality for treatment of viral wart, it is always better that it is done either by a medical specialist or under medical supervision.
Now , in your case you have developed you have developed burns due to excess application of the chemical.
Firstly, keep the area clean and dry as much as possible...Clean with lukewarm water twice a day and apply an antibiotic cream containing Mupirocin
over the lesion atleast twice a day.
You have developed superficial wounds which might take 5-7 days to completely heal,,You can take some oral pain killers to relieve the pain.
Sometimes, if the pain and swelling increases inspite of above measures, you might need a course of oral antibiotics
Hope it helps
