Hi, my mother has stage IV cancer that originated from her bile ducts and have metastasized to her liver and lungs. She has liver cirrhosis as well. I am wondering why she is shaking uncontrollable. Hand tremors started a few days ago, and today they are much worse and it looks like she is starting to lose control of her urinary movements. She has been vomiting a lot over the couple of days, and is on morphine and oxycodone for pain. Thank you.
