I am 16 years old and for a long time i have had a very strong pulse. At night I can feel it going everywhere, in my stomach, fingertips, toes, and other areas. when i lay down, the pulse in my abdomen is extremely strong, i can see it pulsating and it moves my hand. i have been reading and im concerned it may be a sign of an an aneurysem. how common is this? should i be worried? i am 5' 9" and i weigh around 120, so i am very thin. what should i do?
