My mam has bile duct cancer. She is 84 and for the last 3 weeks has had bouts of violent sickness. Dr has prescribed tablets with no effect. She was taken to hospital where she was given anti nausea medication intravenously. This has helped but nausea has returned over night. She has taken the oral version of meds but they’re not really helping. When not feeling sick she is mobile and independent. This is really causing distress.
