Tingly Stabbing Pain in Breast?

Sudden, unuexpected and fleeting pain, often described as sharp, stabbing, electric shock or tingling at three weeks after surgery, is usually healing pains as the nerves repair themselves. It is different than muscle pain or cramping. Pain that is progressive, that is unrelenting and continues to worsen, is more indicative of a problem. Singulair can cause some real problems, but pain in the breast is not one of them. The best thing for you to do is to let your plastic surgeon know what you are experiencing, and let them check you out. Via the Internet, I cannot tell what is going on, or whether this is normal or a problem.

It is normal to have intermittent discomfort after caspulectomy.  This is probably aling normally.  You should follow your surgeons recommendations on implant massage and implant displacement exercises.
