ok so my father came back today and he did the same procedure he did the first time he went, an Angiogram. However nothing was found to be wrong with his heart. So there has to be another problem with my father.

I'm very worried. Anyone know what could it be? My father will yet again go BACK to his PCP and start from scratch again! If anyone has any ideas on what could be causing my fathers problems plz post or give any theories! I asked my father to ask his doctor to check his lung. Thats the only place I can think of right now.
