Why do I feel a mild suction like feeling in the middle of my chest? I am a healthy 15 year old male that gets a lot of exercise everyday. But a few days ago, I felt that feeling in my chest. There are no other symptoms, and it doesn t affect me when I exercise. My anxiety has gotten worse ever since, and it s really bothering me. I drink a moderate amount of caffeine as well, so I don t know if thats a possible cause. I m going to my doctor tomorrow to see what s going on. I ve been extremely anxious these past few days and all that would help me, is reassurance from a doctor. Thank you!
