Hi, I am a 15 year old boy, 6 ft tall , 154 lbs quite thin, BMI 20.3 , I used to do strenous exercise for about 6 -9 months for my badminton training( I left it in august), well now i am off. Recently 3 months ago, i noticed a pulse in stomached , when i pressed down real hard( probably my aorta) . Then about 2 months, I can feel a palpable epigastric pulse, when i hold my breath. I went to the Child speacialist ( family doc) two times, after seeing my pulse( he didnt do a physical examination) , he told that it was normal and just epigastric pulsuation and that i shouldnt worry. Well the epigastric pulse is still present and also when i lie down in bed , i can see my epigastirc pulse. I never smoked, drink and dont have a family history of AAA. What could it be? Please i need help , i am anxious about it and my exams are just a month away.
