The last couple of times that I have done pretty heavy cardio, I have had a fluttery or spasm feeling kind of in the middle of my chest toward the bottom of my right pectorial. I doest really feel like a muscle, but more like something internal. I am a 25 year old athlete, and I have had asthma all of my life. I am going to see my personal doctor tomorrow, but Im curious to see if anyone has ever had this problem and what may be causing it. Thanks in advance!
