Got burned 8 days ago by fire. Consulted a doctor immediately. He gave silverex ointment. But after 2 days 3-4 blisters appeared (side leg part) and now since 3-4 days all the blisters drained in one and has become large. One blister popped when it got touched to table. I only applied silverex cream. Yesterday again I consulted some other doctor he said it?s normal and nothing to worry. But the large blister is as it is from 2 days and itching a lot. Please suggest. Thank you!
