I can feel my pulse in my abdomen to. It is generally stronger when I am laying down. This is normal for some people, especially if they are thin. However, a strong pulse in the abdomen can also be a symptom of a aortic aneurysm. This condition usually occurs in older adults and can be diagnosed by an ultrasound. Get it checked out if you are concerned or have other symptoms.
It may be that you have a neverous stomach.
