Hello, I have a large oval shaped flat to the surface red spot under and to the left of my Right breast. I had some itching under both breasts caused by a moist environment but that has gone away with using cotton bras and better diligence, etc. I did scratch those areas when the itching was intense but generally avoided scratching the area. This condition happened about three months ago but this spot remains. This discoloration is not painful and there are no textural skin changes. The size is approximately 5x2.5 inches.
