Linear Scleroderma. Scleroderma is a rare autoimmune disease in which an overproduction of abnormal collagen causes normal tissues to be replaced with thick, dense scar tissue that can affect underlying bones and muscles if left untreated.
Liver pain. Liver pain is felt in the upper right area of the abdomen, just below the ribs. Usually, it is a dull, vague pain though it can sometimes be quite severe and may cause a backache. Sometimes people perceive it as pain in the right shoulder.
Symptoms often don't appear in the early stages of liver cancer. There are few nerves through the liver, so someone with this type of cancer does not feel pain. Symptoms are the same for both primary and secondary liver cancer. In later stages, liver cancer can cause an ache in the upper abdomen or back.
