Hi, i am 20 yrs old male, i was healthy and my fitness was so good, i have mild PR since i was a child, diagnosed when i was 14, one year ago I experienced shortness of breath and it was constant, a chest and back pains, and when i do a minimum exertion i feel a strong feeling of fatigue and nausea as well as shortness of breath (I AM AFRAID OF HAVING PULMONARY HYPERTENSION) , two days ago i was with a cardiologist and did ECG, and he told me that the regurgitation is the same (mild), and said you're okay don't worry it is psycho factors that made you feel this feeling AND YOU DONT HAVE PULMONARY HYPERTENSION !! And recommended me to play sports and enroll in a gym center, my total concern is, WOULD THIS REGURGITATION GET WORSER? DOES THIS FEELING OF STRESS AND FATIGUE AND CONSTANT SHORTNESS OF BREATH CAME FROM ANXIETY?? I AM REALLY SCARED AND DESPERATE ABOUT MY CASE, WILL IT GO AWAY? And let me be healthy again?
