<s>[INST] Hello! So yesterday morning, I choked on a small amount of seater. Later that day, I did an intense workout and could not catch my breath. I was coughing a little and the center of my chest was hurting. Now I feel very tight in my chest and feel like my stomach is bubbling. I’m having some shortness of breath as well. Did it get into my lungs? Will it go away? [/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Sudden onset of chest pain, tightness, breathing difficulty etc. are suggestive of heart diseases. So better to consult cardiologist and get the blood pressure monitoring, ECG, 2D Echo and stress test (trade mill test) done. If all these are normal, then no need to worry for heart diseases. Sometimes sudden onset of stress and anxiety can also cause similar symptoms. So avoid stress and tension, be relax and calm. Don't worry, you will be alright but first rule out heart diseases. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
