I have a itchy
, sensitive, and bright RED rash
on the underside of my right breast
. It spreads down onto my abdomen. It's roundish, and about the size of a softball. I have large breast and thought intially that it was a heat rash, but even with hydrocortisone cream application it does not seem to be improving. It doesn't seem to be spreading. Is this something to be concerned about?
Thank you, in advance, for your advice.
