What is this weird feeling in my chest I have this warm and tight feeling in my chest. It doesn't hurt but it scares me. I don't smoke. What could this be?

The warm and tight feeling in your chest could be related to anxiety or stress, especially if it doesn't cause pain. It might also be linked to muscle tension or even gastroesophageal reflux (GERD). However, it's important to consult a healthcare professional for a proper evaluation to rule out any underlying conditions.
