Usually there are other reasons for the skin changes, but we do recommend evaluation, especially if these are new, persistent or worsening. Skin changes that cause worry include: 1  Skin puckering or dimpling. 2  Nipple inversion (when nipples indent, or seem to turn inward). 3  Thickened skin tissue, with enlarged pores (known as peau d'orange, French for orange peel, which it resembles). 4  Warmth, pain or redness of the skin.

Much of the time, bad breath comes from the gases produced by bacteria accumulating in the mouth, on the gums, teeth and tongue, said Dr. Jeffrey Spiegel, an otolaryngologist in Boston. Many of these gases contain sulfur, which gives them their stinky smell.
