My Mom, who has severe dementia, has a 'mass' on her lung, which we have chosen not to biopsy (found about 2 years ago)' has recently begun experiencing severe pain in her left arm, professing to below her rib cage most often on the left side and most recently pain in the left side of her groin. She has a low dosage fentanyl patch (12 microgrograms) for sciatica. She has had significant weight loss, loss of appetite, extremely low blood pressure 90/50. My Mom is 85, and I'd just like whatever I can do to make her comfortable.
