What causes shortness of breath and tight sensation in the chest?
Patient: About a month ago I went to ER for shortness of breath and chest tightness. They did all kinds of major tests on my heart. Everything is fine. I did feel better for a few weeks but now the feeling is back and worse. I m waiting for my pulmonary doctor office to call and make and appointment. Can you help with any ideas to what may be causing this? Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. For chest tightness and difficult breathing heart tests are normal So further work up done in the form of chest X-ray and spirometry to rule out respiratory causes.  If respiratory cause also not present than history about muscular strain has to be taken Excess anxiety also can lead to such presentation Take care Hope this will help you.
