Discussion: Apart from the brain and liver, most of the major organs in the human body are pain-sensitive.

We can feel pain in our bodies almost anywhere possible. Although there is no "brain" pain, migraines are one of the most troublesome; they are not brain pain but intracranial pressure. The liver has no pain, but the gallbladder and nearby organs have pain sensations. The pains of chronic liver patients (like me) are terrible because the body rots! But this is not a pain of the liver itself. If the liver were a painful organ (similar to the heart, for example), everyone would live in pain because of the diet and the unhealthy modern lifestyle.
