I ended up in a surgical assessment unit today after severe abdominal pain, loss of appetite, weight loss, nausea and diarrhea. I had blood tests which were "reassuring" which is good, but the registrar could feel some hardening in my mid abdomen so I had a CT scan. This came back clear apart from gallstones and an abnormality on my liver which needs further investigation with an MRI and possibly a biopsy. Can anyone help with what "an abnormality" might mean?
