Hi my partner has, about 6 weeks ago had cancer of the asophagus removed, the operation was a complete sucess, he has had two water infections though since then, and has had two weeks of antibiotics , which dosnt seem to have cleared it, it is still abit painful when he urinates, his urine a brown colour,and he has trapped wind in his stomach ,which makes a loud bubbling noise, which comes and goes. He is sometimes sick, when he over eats i would say, as he gets a little giddy with food, as he went a few month hardly being able to eat. He is putting weight on now, slowly but surely, last night though he was sick black vomit , which is worrying also, what could this be, and do you think he may need to go back in hospital , put on a drip of antibiotics to clear up the infection? Thanks.
