Yesterday at, evening mother was fine.but at night after taking dinner she got pain in lower ribs and upper back . About at mid night ,then she drunk alot of water and thought that it's an acidity so she taken "aciloc" tablets . But after taking alot of water and after alot of walk she didn't got relief .one more thing she experienced that when she try to sleep and she was lying on bed the pain increases. Then at 2 at night she went to hospital .There doctor had given her an injection and a tablet due to which she got relief and thus,she was able to sleep .But now she is feeling tired and energy less .. So please please ,tell me that what are the probable reason for this ...
