In 3 directions (sup, lateral, inf to nipple, + lateral nipple) it looks the same as when a blister bursts and new skin is exposed-- raw with granulation tissue. Started 3 days ago as a pink line adjacent to aureola, now is about 1/2" wide in each direction. How should I take care of this? (triple antibiotic ointment, cover w/ non-stick pad vs. letting it dry out? Shower vs no-shower for a few days?)
