Should I keep bandaged for more than 3 days after procedure - if I have newly popped blisters? (photos)

I received the treatment on Monday. Went back Wednesday to get the blisters lanced and have continued to change out and wear bandages with antibiotic and gauze until today, Sunday. My Dr. told me to keep it bandaged, covered and continue using a compressor sock "until it has healed." Nothing has scabbed over - and I wonder if that is because I am keeping everything covered and moist. I also don't want to risk infection because the blister skin is very thin.
