hi suzette,
i found your posting -- and this site -- by googling a chemo-related joint pain inquiry. i was diagnosed w/stage 2a colon cancer in april of '06, had an emergency resection, followed by colonoscopy, then four months of chemo (twice a week, every other week, oxypl/5fu/leukovorin cocktail), which concluded at the end of sept. although i had slight neuropathy during chemo (numb fingers and toes), i considered myself fortunate that i lost no weight (tho i certainly can stand to lose a few lbs, my wonderful chemo nurse told me that the odds of having a positive chemo experience were in direct relation to not losing weight), lost no hair, didn't suffer, as did some in my support group, from black nail beds and joint pain. then chemo ended, and although i cannot remember exactly when the joint pain hit me, i share your frustration w/doc's not being completely forthcoming abt side effects: this joint pain is incredibly...well, painful. it's better tha more i move, and mornings (or after having sat for five minutes or more) are most difficult. week after week i would ask my doc about the pain, and he finally conceded that it was chemo. thanks.
like you, i am eager for it to pass, and although exercise is no picnic with this pain, i do think increased circulation helps aleviate a bit. my neuropathy has also gotten worse, and i look forward to that going away. mostly, though, i pray every day that i am never again visited by this terrible illness. best of luck to you.
