This is by no means a definitive answer. Consider however that the capillary leak occurs in diverse organs for no known reason. Many experience peripheral muscle oedema causing swelling, arterial occlusion and progressive muscle death. My leak occurs into my lungs. Others suggest pericardial or brain leaks. Perhaps yours is into the liver. Now the lived is encased in a tight fibrous membrane and any internal swelling will cause arterial compromise to the liver cells, hence raising enzymes. It is important to realise that a raise in enzymes represent damage, but not death, of liver cells.
The symptom you would get is liver pain.
This may or may not explain what is happening with yourself.
