Discomfort, fullness, pulsating.

I am 28 male and overweight, i'm currently on atenonol which was prescribed when i had a spurt of high-blood pressure and palpitations 2 years ago, and i now continue to take, I had numerous test to confirm their is nothing wrong with my heart.

I have recently found a very strong pulse within my abdomen, this can be felt as a vibrating at times when laying down but is not always there it varies in strength, which tends to be stronger at night.

When lying down and pushing quite hard into my stomach, i can feel a strong pulse the pulsating does get harder and stronger coinciding with rest and movement, and can be felt from the rib cage to the left of my belly button i have no abdominal pain in that area. but do have discomfort and a feeling of being full all the time.

Many Thanks
