Mastodynia is a medical term that means a patient suffers from pain in the breast. Sometimes the pain is associated with the menstrual cycle, but for some people, mastodynia is a symptom of an underlying disease. Occasionally, a patient may have breast pain that has no identifiable cause, although such simple causes as an ill-fitting bra may be found to be the problem.
Pleurodynia is an uncommon complication of coxsackievirus B infection.
