Hello and welcome to e health forum.
The bruise seen could be due to a incidental injury, that you might have not remembered.
Since you do not have any symptoms, you need not worry about it.
Applying a thrombophob ointment and use of medications like Advil, might help in quick healing of the bruise.
Bruising is not a classic indicator of liver disease.
The more common signs of liver disease include - nausea, vomiting, right upper quadrant abdominal pain, jaundice (a âyellow discoloration of the skin due to elevated bilirubin concentrations in the bloodstream ) , Fatigue, weakness âand weight loss. â
In case you have the above mentioned issues, you should consult with your doctor for a examination and proper treatment.
