Hi Traci & Traci's dad!
I had surgery in May '07 (resection). Immediately after the surgery, I asked a very young nurse how soon I'd be feeling stronger. She said "Oh, about 6 weeks." (oops,she was very wrong!) The incision was healed quickly, but that was all that happened soon.
Both the surgeon and the oncologist said that it would be AT LEAST 6 months until I felt stronger, less fatigued and my system could establish its "new normal". It actually took about 7 months...but by then I was on chemotherapy and that made me feel fatigued, too.Tell your dad that he will gradually get stronger and he'll be walking without a walker in good time...but he must give his body a chance to heal. Ask doctor about gentle exercise (I used to go for several short walks each day (until the cold weather/snow/ice season hit here). Feeling much better than I did in those weeks following surgery; but still have a long way to go.
About taste.... That terrible aftertaste started with my 2nd chemo infusion (FOLFOX4).Not a metallic taste as some folks describe.... but just a really awful taste especially when I ate even the tiniest amount of sugar...even the natural sugar in fruit/vegetables caused this.Strangely, "Splenda" sweetener did not cause this aftertaste....hmmmm.
Initially this would occur for about 2 days after chemo; then it went away. But by treatment # 5-6, the bad taste didn't go away at all. Suggest dad might experiment with different kinds of food. I've heard lots of people have luck with spicier food. And, since "sour" is the last taste sensation to go, I discovered, quite by accident, that good crunchy dill pickles were about the only food that tasted "normal". Celery with cream cheese was good too. Suggestion made in earlier post of eating many tiny high caloric "meals" thru the day is a good one. The cancer cookbook I was given at cancer center said to avoid any "favorite" foods which make the patient ill. This is so that that smells and tastes of those foods will not become "associated" with feeling sick once the chemo ends.
Hope these things will help you.
