I called Dr. Shaft's office and his PA said it sounded like Dressler's (chronic inflammation) because I did not have the pain until about 3 weeks post op. My local dr. in Florida did the blood test to confirm this and it was negative. He tried a regimen of steroids but I still have the pain some nights worse than others. At this point, my local doctor said it is all part of the healing process. I am reaching out to see anyone else has had this experience. The pain is the worst when I lay down on my left side. It hurts in my heart and goes around to the start of my back. Not sure if it the lung area or the back of the heart.
