Hi Laura or anyone with the same interest: My father had surgery on his heart 8 years ago and ever since has been having severe chest pains and has now been diagnosed with blood clots in the lungs. They have him on blood thinners and morphin for the pain (which isn't working). does anyone have any suggestions or information on this condition. I am worried to death that when he has a chest pain he isn't going to make it though it. If there is anything that can be done we will do it. Thanks for you help.
