The duration of the pain that you mention is of concern. Eventhough you
have had normal endoscopy
and normal ultrasound
, the symptoms do
suggest that you do have some upper intestinal problems. The mention
of greasy foamy stool suggests that you have problem digesting fat.
This might happen when your pancreas
is not functioning properly.
Repeated attacks of inflammation of the pancreas can cause this type
of damage and the condition is called "Pancreatitis
". Eventhough the
most common cause is gallstones, other conditions can also cause this.
This could be alcohol related or viral infections . I would recommend
that you see a digestive disease specialist who can perform aditional
testing to look for problems with pancreas.
