I had a double mastectomy with reconstruction in 2008. For the past 6 weeks I have had a cough that comes and goes. One week ago I sat up and started coughing and got a sudden severe sharp pain just below my left breast at the top of the rib cage. I get the pain off and on, mostly on the left side. It is worse when I am sitting up. Today for the first time I had the sharp pain almost between the breasts but a little more in the right. It only happened once and lasted for a few seconds. When I m sitting up straight it feels like my ribs are pushing up into my breasts. There are also times my implants feel like they are on a brace and push up toward my neck. Is it possible I cracked or bruised a rib due to coughing and that is the cause of my pain?
