I have 6 stents and have been having difficulty breathing for over a month. I went to the ER on Wednesday for my shortness of breath. Friday my cardiologist said he wants to do a heart cath on Monday to rule out my heart. My breathing continues to be bad and tonight my feet feel funny when I sit, they get better if I put them up in the reclining chair foot rest. I can t tell if they are swelling up or not, but I just want to make sure it is nothing with my heart. I have also had 2 surgeries for acid reflux and have had breathing problems before those surgeries. My wife and I don t know if I should go to the ER again or wait until Monday s heart cath.
