hi sorry that you are having a hard time. Its sounds like you need to get another surgeons opinion about redoig the fundo, as it can be successfu if done correctly and maybe antoher surgeon could redo it for you and help our problems.. dont give up there is always a solution im sure!!!
have you tried the reverse theory which has helped heaps of people.is taking raw apple cider vinager as some people are actually low in stomach acid so taking PPI are bad for them as they need more acid not less............
its sounds like your swelling could b fliud retentin, you can try natural methods to help this along with reducin salt intake etc
im not a doctor and am strugling with my own medical stuff but i do think seeing a new surgon/doctor for a fresh approach may help
good luck ness
