I am large of nork, therefore my breasts have a fair bit of overhang. Sometimes it gets quite humid under there (it’s own microclimate). Yesterday whilst washing under there I noticed it was very sore and there’s about a 1.5-2 inch region of sore, broken skin. My immediate reaction was to keep it dry so I applied talc, but then later on decided to switch tactics to sudocrem. As soon as I start to sweat a little under there, it stings like a bastard. Is there anything I can do? Thank you
