Hi, greetings. Would be interesting knowing if this is the first tome you are experiencing this feeling. However, if its repetitive, you might need to consult a internal medicine specialist. Blood electrolytes (Calcium, Potassium, Magnesium) would be worth carrying out, with respect to your chest pain, a pain in the chest must not always be or cardiac or heart origin. Other structures in the thoracic cage could cause pain when attained, and a pain from another area not even the chest could be falsely felt as if it it comes from within the chest. A more critical analysis of the pain needs to be assessed, a good cardiologic, pneumologic and an internal medicine consultations could be of help. I think you need to reviist your internist and probably a pneumologist for proper reevaluation and care.They shall decide whether you meet a cardiologist or psychiatrist if need be. Be well, Luchuo, MD
