My mom has been diagnosed with metastatic pancreatic cancer around 2 months back. She was not willing to go for chemo sessions. Hence we opted for palliative care. She has been vomiting whatever she is eating for the past day. The doctor has suggested not to give her morphine as it would increase the bout. The medicine given to her to control her vomit isn't working. What should we do? Also what pain medication should we give her now that morphine is not an option. Please help.
