Just recently, I started getting this flutter in my chest. It will happen maybe once or twice a week and it feels like theres a butterfly in my chest flying around. I can t tell if it s my heart or upper airway. It creates this feeling in my throat that I have to cough. This all happens in about 5 seconds and then its gone. i was adopted so i don t know if this is due to a family history of heart problems. I am only 20 years old.
