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

Patients with chronic kidney disease must pay attention to their liver function because the ability to repair liver cells is much higher than those of the kidneys and is critical for kidney rehabilitation. Patients with chronic diseases of the kidneys do not have early warning mechanisms in the absence of pain in the liver.

We can feel pain in our bodies almost anywhere possible. Although there is no "brain" pain, migraines reflect 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.
