Something is "not right" with my heart surgery

I have been reluctant to talk about this for obvious reasons, but this morning I decided to let all of you know that something is not right with my open heart surgery, done on April 25.

No matter who I talk to about what's going on, the answer is always the same: "It's normal."   Well, it's not normal to me.

What I'm encountering is best described as a failure to heal.  Inside my chest, toward the bottom third of my incision, BEHIND MY RIB CAGE is still painful a full four+ months after the surgery. 

It encompasses the area of my diaphragm and about three to four inches around that diaphragm.

To this very moment, if I cough or sneeze, I get substantial pain in that area.  It's as though the healing somehow stopped and that surgical pain is not halting.

To put this in perspective, I am NOT taking any pain meds for it. Not even aspirin, ibuprophen, or tylenol.   It's not a terrible pain and it only happens when I sneeze or cough.  But when it happens, OH BOY!

Personally, I think there is some type of infection taking place, although I have no redness outside, no tenderness to external touch, and no fever or sweats.   I'm thinking fungal.

But the docs all tell me the same thing: It will get better, you just need more time.   Well, I think that's bullshit.  The rest of me healed.  I have no pain anywhere else.  Why is this particular area still painful?

I mean, for goodness sake, other than traumatic BRAIN injury, I do not know of any part of the human body that takes four+ months to heal.  

So I'm in a quandary.   I feel that something is wrong, the docs say it's normal and I think it isn't.  What to do?
