I'm a 21 year-old, healthy female. I don't smoke, nor do I drink.
My stomach has been pulsating for the past 3 months, akin to my heart beat. Its most noticeable when I'm laying down, its locating in the upper right quadrant of my stomach. I've been to the doctor and the ER and they told me that my aorta was a normal diameter by way of an ultrasound, and gave me a rectal exam to make sure I wasn't bleeding. But they didn't have any answers for me and they sent me home.
My stomach is still pulsating and I don't know what's causing it. Any ideas?
I've also noticed in the past 2 months, that every bowel movement I have, have consisted of small pebble-like stools. I have them regularly every day, and I keep myself hydrated so I don't think I'm constipated. Not sure if it relates to my stomach pulsating, but I'm not sure what's causing that either.
