rash on breast

I seem to have developed a rash on my left breast.  The 'elevations' look like bad acne in size.  It doesn't itch, but when it first showed up and the elevations were smaller, it did.  I haven't changed clothing detergent or deodorants or anythhing.  My stress level has gone up EXPONENTIALLY  in the last few days, so I'm hoping that's all it is!
I noticed it this morning when preparing to shower, as I do a 'skin check' just prior.
Any thoughts?

Hi.
Skin diseases can occur also on the breast.  The cause can be multifactorial.  Most of the time, it starts with a small lesion then gradually enlarges.  Symptoms vary from itchiness to pain and tenderness.  Stress can aggravate the pre existing condition.
It would be best to consult a doctor so that full evaluation can be done so that appropriate treatment can be started.
Good luck.
