Since yesterday I have been having stabbing pains in my left breast. Started last night when it bed, it happened twice so I rubbed the area to see if it would stop the pain but that just made it hurt all over. The pains have just started again now, feels like a shop stab or someone thumping me hard in my left breast. I don't have any lumps that I can tell or any discharge or anything. Just the annoying pain. Anyone else get this?
