I'm having the same issues, and thought I'd Google it to see what I find. I'm 55 and overweight and definitely not pregnant, but I've been having sudden random pains in the right side of my belly just below my rib cage. Mine is a sudden sharp pain out of nowhere. Just had one while sitting here on the sofa with my laptop and found this site. Strange and kinda scary. I've had gastro problems for years now and have a colonoscopy and endoscopy every few years. I still have my gallbladder. I've had left pain/tenderness for years on my belly and have had a CT and nothing could be found, but this is something new on the opposite side. Getting old sucks.
Wow, I read thru so much on this site, but yours was the only logical one to me. I too had an ultra sound and am waiting for results, however parasites seem so reasonable to me. I have no place
I can think of where I got them, but understand and appreciate your description. I will look into this for sure. It drives me crazy too.
"The small intestine dumps waste through the ileocecal valve (ICV) on the right side of the body into the beginning of the large intestine. The large intestine travels up the right side of your belly the across the tummy, where it dumps waste into the descending colon on the left side.
Sleeping on the left side allows gravity to encourage the food waste to move more easily from the small intestine into the large intestine through the ICV.
As the night wears on and you continue to sleep on your left side, the waste moves more easily into the descending colon. With the help of gravity and a good night’s sleep on the left the side, the descending colon is full of waste to easily eliminate completely each morning."
