Welcome to the site no one wants to find. Where are you located and what treatment are you seeking? It's important early on to really get moving on a treatment plan involving one of the major cancer centers. There's not too many cases a year (~2000 in the US), so only big city care has the requisite experience.
Regarding, the gas, I would consult a nutritionist, since a diet change may help with that and the pain. The only symptoms I experienced were bright yellow skin color, very dark urine color, and fierce itching with no rash everywhere, but zero pain.
I live on the Eastern Shore of MD and was operated on 4/2009 at NY Presbyterian in NYC, so convenience was way down on the list of priorities for me.
Good luck in seeking care.
