I'm feeling really worried because I've been experiencing chest pain whenever I walk or exert myself. I had a TMT test done, and it was negative. They tried doing a PFT test, but it couldn't be performed. My X-ray came back normal, and the 2D echo showed 60. What could be causing these chest pains despite all these tests being normal? I'm really concerned about what might be happening.
Do Troponin test, need detail history , can guide
