Suggest Treatment For Severe Pain In The Abdomen While Treating Stage-4 Esophageal Cancer

Question : Hi, my wife has stage 4 esophageal/gastric cancer and we have been getting chemo treatment for about 15 months now. Primarily with 5fu and irronoclan combined with cyramza every other week. She had an infection in her med-port that resulted in a 3 week ordeal in the hospital to remove it, get rid of the infection and manage the pain that spiked out of control, we are now home on hospice. I guess the blood numbers went down and treatment is not now a viable option anymore so we were sent home with the pain managed via morphine and methadone. My questions are this, what should I do to check on other treatment options rather than wait to die? She is still eating, still fighting but the pain in her abdomen and back area where the lymph glands are enlarged, is going to get harder to control. The cancer seems to reside in the glands primarily in a belt around her lower torso. Is there any oral pill form she can take to fight this type of cancer? My insurance company was willing to carve out a payment to the oncologist to continue treatment while still going on hospice as a form of pain control. It seems the oncologists office declined to submit for authorization because they had not been paid in a similar instance and treatment and hospice are mutually exclusive occurrences. Also stated they did not believe the treatments to be effective anymore. I have no clue about any of that other than the insurance was willing to give it a go.Any advice? Are there any other type of pain blocking treatments to seek besides morphine, like a nerve blocker or something? The main problem seems to be the cancer growing inside the lymph glands and causing pressure (thereby pain) on the surrounding area. Is that approximately the right way to think about it? Thank you for any direction you can point in or advice on how to proceed. We knew the treatment was palliative not curative. but prior to the infection we were coasting along with a pretty decent quality of life and then bam, we're done. XXXX XXXXXXX
