I had bypass surgery 8 months ago. I have almost constant pain in my chest.

Hi Nancy: Hopefully the Doctor present will anwser your ?.....I had some discomfort for about 8 months but no real pain. Sorry,don't know what keloids are..........but check with your Doc. on the pain. There's many good things that can help. God Bless

My first bypass was in 2000 and complained of the sternum pain along with the angina I was also experiencing.  Of course the doctors were doubtful of my complaints until I went to UCLA.  The original doctor didn't do a proper job so I had to go through what they call a re-do.  To this very day I still have chronic sternum pain.  Of course there are meds but who wants to live like that.  I hope you are feeling better if not get another opinion...please!
