Breast Discomfort: At some point in time medical help may be needed if the discomfort persists, especially if a discharge of pus or blood from the nipples occurs, or there is any sign that an infection may be present. Although breast discomfort for short periods of time, such as cyclic discomfort can be regarded as normal, though irritating, if the discomfort persists for a long period of time, seek medical advice.

Need exam: Impossible to know the answer to this without an exam and detailed history, but you can try some "udder cream" often available in health food stores. If that doesn't help, you'll need to see a dermatologist.

Breast pain: Mastodynia or breast pain can have variety of causes. Most commonly, hormone fluctuations can cause pain. Fibrocystic disease can also be painful and related to hormonal levels. Less common reasons include infections or inflammatory conditions. In older patients (ie. In the fourth decade of life or greater) an advanced cancer can be painful. See your physician for a good history and physical.
