Re: pain with port. Perhaps pop in the chemo unit day before. I used local anesthetic cream 1 hour before (can't remember what it's called now ) so port didn't hurt when they accessed it.
Re: before hand I would suggest something quite fibrous like nuts and dried fruit (I got constipated on AC). After I ate what I tolerated. Nothing spicy. I craved salty foods. I eventually needed movichol (for constipation) started 1 day before AC treatment and continue 3 days. Worked a treat.
I was told to avoid soft cheeses, cultured yoghurt, shop prepared salad (coleslaw etc) and reheated takeaway food, smoked salmon. Anything tbat might have bacteria or lysteria risk.
I could have fruche, bacon, hard cheeses, fresh salad so all not lost.
Hope goes well.
