I read in the encyclopedia brittanica a while back that there are three unique organs in which they are unable to receive pain signals two of them are the brain and liver i tried looking up and down to find the third one but i couldnt find it. Im starting my first year of undergraduate school this year and i plan on being an anesthesiologist i am disabled with a number of conditions and i guess thats why i want to be a doctor i currently work at barnes/wash u in st louis in the clinical research sciences building and my badge says casey n******* and under it it says surgery so i guess that would make me a 18 year old surgeon 😛 but i work in minimally invasive urology which is very unique and i really like it. but there might only be two that do not pick up pain because i was on benzodiazepines because i had panic attacks from pain bc i had a full spinal fusion. also i know this isnt a cardiology board but if you know what marfans syndrome is plus 1 for you and yes i have marfans.

While I am not certain where this "3 organ" idea came from, most of the abdominal organs are insensate to standard pain/temperature stimulation. The hollow viscera (intestines, ureters, bladder, uterus) are sensitive to distention. Irritation and inflammation of the capsules that surround visceral organs will lead to painful stimulation, though often this sensation is referred to other areas of the body. For instance, irritation around the gall bladder will be perceived as pain under the right shoulder blade.
