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

The heart is a pain-sensitive organ that creates a deathly fear, sometimes paralyzing.

We can feel pain in our bodies almost anywhere, including the heart. Although there is no "brain pain," migraines are one of the most troublesome. (Migraines are not brain pains but the result of 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 horrible because the body rots! But this is not a pain of the liver itself.
