i have been having sharp cramps in my abdomen and sore breast

Hi,

This information should help you understand your abdominal pain: http://www.nlm.nih.gov/medlineplus/ency/article/003120.htm

From MedlinePlus link above:
"The intensity of the pain does not always reflect the seriousness of the condition causing the pain. Severe abdominal pain can be from mild conditions, such as gas or the cramping of viral gastroenteritis. On the other hand, relatively mild pain or no pain may be present with life-threatening conditions, such as cancer of the colon or early appendicitis."

Please call your doctor today, as anytime a "sharp pain" is described, it is best to have this checked out quickly, to rule out anything serious. From the link above, you can see there is a litany of possible causes of abdominal pain, and it is important to know the cause.
