We can feel pain in our bodies almost anywhere possible. Although there is no "brain" pain, migraines are one of the most troublesome. 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.
