I'm really puzzled about something and could use some guidance. All my testsECG, echo, and TMTcame back normal, yet I'm experiencing this weird pain in my chest muscle, especially when I touch it or sit down. There's also this mild pain below my collarbone and at the back of my left rib when I touch those areas. It almost feels like there's some swelling right below my left collarbone, but everything looks normal when I check in the mirror. Any idea what might be going on?

Based on your description, it seems like you may be experiencing musculoskeletal chest pain rather than a cardiac issue since your ECG, echo, and TMT are normal. The pain you are feeling when touching your chest muscles and the mild pain below the collar bone and back side of the left rib could be due to muscle strain or inflammation. To help relieve the pain and swelling, you can try taking over-the-counter pain relievers such as acetaminophen. Additionally, applying a warm compress to the affected area and gently massaging the muscles may also provide some relief. If the pain persists or worsens, it would be advisable to consult with a doctor for further evaluation and management.
