Hey, I am 18 years old and for the past two days I have been experiencing a problem. Whenever I sit down, an inch below my belly button there is a thumping, somewhat as if someone were kickign from the inside. There is virtually no pain whatsoever, but when shirtless I can see my stomache pulsating/thumping. I do not know what it could be because I have not been eating anything weird lately. If someone could please try and help it would be greatly appreciated.
The thumpign is not constant, it is sparatic but happens numerous times in sets, per hour. It feels as if the stomache is rumbling but for an extended period of time, these sets go on for abotu 5 to 10 seconds each and feel sort of liek vibrations
I went to thedoctor recently about the same thing. Seems as if i am just skinny and it is my aorta I can feel. once you notice it..you notice it more! You are more focussed on it.
If you have radiating pain with it especially in between shoulder blades, contact a doctor, but due to your age it is very unlikely to be anything other than your pulse you can feel.
I hope this puts you at rest.
