My husband is 73 and was diagnosed in July last year with Esophageal cancer. He had a stent fitted at the hospital a week ago. He was kept in two nights due to severe pain. when he came home he expected to be able to eat tiny amounts of mushy food, but has been unable to as he is burping all the time and is in extreme pain. He has been sleeping sat up in a chair each night and just sipping milk. He. Has Ben given liquid paracetamol but it hasn’t made any diffference why is this happening?
