<s>[INST] I have a red, raw line along the whole under-fold of my breast.  Had red ring/yeast infection on underside of other breast 2 weeks ago....now the left side is raw all along the fold.  I have applied Nystantin, and another steriod/yeast cream...nothing helping so far.  What should I do? [/INST] Hello Madam, Welcome to Chat Doctor. I read carefully your query and I understand your concerns. The condition you are describing is called "intertwine", which is characterized by a rash that shows up between the folds of skin. Being that you are already on steroids and antifungal medications, I would recommend you start an unguent with zinc oxide, which is used for relief of rash. For further prevention and for quicker relief of the actual condition I would recommend you to shower and Chat Doctor.  </s>
