I've been getting some pain on both sides of my chest from time to time, and I'm a bit worried about what it could mean. I had a chest X-ray recently and it came back normal, but can an X-ray really tell if there's something wrong with my heart or lungs? Would it show everything that's important, or should I be looking into other tests or something?

Chest x-rays are primarily used to visualize the lungs and surrounding structures, so they may not always detect heart problems. Since your chest x-ray came out normal, it is unlikely that there are any significant issues with your lungs. However, if you are experiencing chest pain on the right or left side, it is important to consider other factors such as muscle strain, rib issues, or even potential heart problems. I recommend consulting with a healthcare provider for further evaluation and possibly an electrocardiogram (ECG) to assess your heart's function. If the pain persists, you can take over-the-counter pain relievers like Acetaminophen (Tylenol) as needed, following the recommended dosage instructions.
