Liver conditions symptoms and conditions

My husband was recovering well from hepatitis A. He's been bothered by some GERD-related digestive problems so he tried OTC Omeprazole because he didn't find any contraindications for liver conditions on it. He took 20 mg daily for 3 days, suddenly felt too full and had no appetite, stopped it but tried again 3 days later when he started having stomach discomfort again. On the 4th day he complained of stabbing pain in his stomach. The next day he was exhausted, bloated,and had a tickling irritation in his throat, and swelling in his feet. He'd had none of these symptoms before taking Omeprazole. I did some research on the Web (at physician's sites) and learned that it is very bad for people with liver problems -- it suppresses key liver enzymes and remains in the body for a very long time. That's been 10 days ago now and his symptoms continue -- mostly fatigue, bloating and swelling in the feet. He never experienced ANY of these things before taking Omeprazole! I see by postings that many people do experience these symptoms for a very long time.
