I've been experiencing a sharp pain on the left side of my chest for a few seconds when I'm exercising, like jumping or running. It's been happening since last week. I've had an ECG, 2D echo, and TMT done last month and everything came back normal. I also get gas pain in my chest. But this pain specifically seems to come in the morning while I'm working out. Should I be worried that this is something serious?

Based on your description, it is possible that the chest pain you are experiencing during exercise could be due to musculoskeletal causes or related to gas pain. Since your ECG, 2D echo, and TMT tests were normal, it is less likely to be related to your heart. To help alleviate the gas pain, you can try over-the-counter antacids like **Tums** (dosage: as directed on the package) to relieve gas and bloating. Additionally, for musculoskeletal chest pain, you can try taking **Ibuprofen** (dosage: 400mg-800mg every 6 hours as needed) for pain relief. However, if the chest pain persists or worsens, it is advisable to consult with your healthcare provider for further evaluation and management.
