Earlier today I had a sharp stabbing pain just left my sternum. It hurt most when I breathed and or breathed out. I held my breath for about 30 seconds and the pain stopped.I have had this happen before on several occasions. But today has been the worst. I am just worried that it may be something worse than just a cramp or something.
HiAny pain in the chest or radiating,it's better to evaluate,can be due to cardiac or respiratory tract problem or bony pain.Kindly go for an ECG, echo and chest x-ray  and consult your doctor.Avoid spicy foods,take plenty of water and oral fluids.Antacids like gelusil will help.All the best.
