<s>[INST] I had chest pains and it was hard to breathe.  I went to ER where they did a CAT scan of my heart, did an ultrasound and found nothing.  INow my pain is in my upper chest area and it hurts to breathe deep, feels like someone is has a bear hug around my upper chest [/INST] Thanks for your question on Health Care Magic. I can understand your situation and problem. In my opinion, we should first rule out bronchitis in your case. Because bronchitis can cause similar symptoms like breathlessness, chest tightness, pressure, pain etc. So better to get done PFT (Pulmonary Function Test). If PFT is normal than no need to worry for bronchitis. Your CT thorax is also normal. So no need to worry for lung infection too. Sometimes stress and anxiety can cause similar symptoms.. So avoid stress and tension, be relax and calm. Consult psychiatrist and get done counseling sessions, try to identify stressor in your life and start working on its solution. You may need anxiolytic drugs too. Don't worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks. </s>
