Thanks for posting your query.
Decompensated liver disease
may cause decrease formation of clotting proteins in damaged liver with increase tendency of bleeding.
But if dark red blotches is forming due to liver disease, then there must be yellow discoloration of eyes and urine, loss of appetite, weakness and fatigue, edema in whole body and recurrent vomiting
You should consult with internal medicine specialist/ gastroenterologist and should go for thorough check up.
You should go for complete blood count
, liver function test, bleeding time
and clotting time, prothrombin time
You should avoid injury to protect yourself.
If liver function test is found to be normal, then there appears to be possibility of simple bruise and it may take 10-14 days for complete recovery.
