Water in lungs is probably from the heart disease. When heart can't pump all the blood which comes from the pulmonary artery, than pressure in lung arteries rises, and the fluid leaks out of them into lung.
He should have breath test, or maybe better blood test for Helycobacter pylori bacteria in his stomach. This is really frequent cause of this stomach burning. Treatment is with antibiotics.
Upper endoscopy (gastroscopy) is the only thing which would show what exactly is in his stomach. If ultrasound is negative, that doesn't mean much, since it isn't pretty accurate.
So - he has to be checked for H. pylori.
Hi, Thank You for the quick response.
The pain in his stomach is like heart burn. He always says its burning. The heartburn medications have not helped at all. The burning pain is always there, only morphine helps. I have not heard anything else about the gastro problems. I'll try to find out about it today.
I just heard that he now has water in his lungs.
Morphine will not damage his kidneys, there's no symptom regarding kidneys in morphine side effects list. This pain in chest seems to be angina pectoris - from narrowed coronary vessels.
High white cells are sign of inflammation, which is not necessary an infection, and may be located anywhere in the body, it may even be a part of a heart disease itself.
This antibiotic thing sounds to be judged quickly; it's weird.
It would help a lot, if you can say what exact abdominal pain he had, where the pain was located, what triggered it (meal, exercise), was it cramping or dull pain, did it persist during night. Any other gastro symptoms, like diarrhea, blood in stool, what is the color of stool?
It's possible he's allergic to that particular type of fish. In allergy, there is a release of substance histamine, which dilates the vessels, and hence cause the drop of blood pressure. This causes diminished blood supply to the heart, and from here the heart pain. Well, this is my theory. Allergy may be confirmed with a skin test, but he should know, what exact type fish it was. If it was spoiled fish (not stored properly before cooking), histamine could built within it and caused exact the same symptoms as in allergy, but this is not allergy and in this case allergy test would be negative. It's called "scombroid poisoning". Leukocytes are also rised in the allergy. Abdominal pain is not characteristic for food allergy, but this pain was maybe triggered the same way as the heart pain - from reduced blood delivery into intestine after the blood pressure drop.
I recommend skin test for allergy to that fish.
