The liver capsule: Which is the thin layer of internal "skin" that surrounds and encloses the livwer does have nerves that sense pain. So if there are areas where the liver is expanding due to smaller lesions or these are close to the liver's capsule then there will be visceral, usually dull vague pain. Other internal structures, like the biliary system (bile ducts) can cause pain if they are blocked. Best wishes!
