cancer.net side effect, Radiation

Hi everyone,  I have been watching the board.  I have CUP that has been treated as intrahepatic cholangiocarcinoma for the last 13 months.  It started as a radiating pain in the left hepatic lobe and biopsy was adenocarcinoma.  Tumor was 4.3 cm.  I am at the largest cancer center in the U.S.  I finished 2 weeks today with 10 days of radiation to a lytic lesion metastes to my T6 spine.  I was told that it would burn my esphogus  but I should drink milkshakes and drink the medicine that they prescribed to deaden my esophogus.  This is without a doubt the most difficult experience that I have had.  The pain when swollowing was almost unbearable, and I am tougher than a Texas Boot.  I went to my local emergency room for IV fluids on Monday for dehyration.  I had vomiting and diarrhea since 4 days after the end of treatment.  I am finally starting to feel better, and am drinking as much gatorade,water and tea as I can.  I can eat a little soft food now, I am very hungry, but cannot eat due to the pain.  I also started TARCEVA 2 days after radiation started.  I felt considerable burning pain in my entire abdomen about the same time as the vomiting and diahrrea started.  My onc said to discontinue the Tarceva and it was stopped 6 days ago.  Everyone is different and I don't want anyone to think that everyone goes through what I have with the therapy.  I have had Gemcitibine, Cisplatin, and Folfox 6 and had virtually no side effects with these chemos.  I have written enough for now.  I have prayers for all the people with this
and hope that researchers can destroy it.
