OK.....well, i don't really think it matters what you do and the above posters are quite correct.
What would i do?
As you haven't told me what the dressings consist of, I would use Tulle Gras dressings (which you can get from the chemist) and change them everyday for another 3 or 4 days and then after that, leave it open and just put the dressing on at night.
From the sound of the damage and assuming you are not an old person, it should settle down within a couple of weeks.
The pain is a concern...."bash" the Ibuprofen.
if the pain gets worse over the next few days and the area around the burn becomes red and tender......go back to A&E.
