Hi Pam, your description of PN is spot on.. Usually the nursing staff ask about it each time you step in for treatment. Depending on the description you give to how the treatment will be administered on the day..
I would seriously be getting someone to pay attention as if you are still on treatment at the moment they really need to know.
As for the fluid, I often have odema in my legs during treatment. My onc adjusted things including fluid intake during treatment to assist with the issue. If it gets worse the med team need to know this too as they can use meds after treatment to keep the fluid retention to a minimum.
As for the stairs, this can be treatment or the fluid or both.
Sounds like you are having a rough trot indeed.. sometimes all of these things can be managed but with assistance of the med team. There may be some discomfort until treatment is over but they need to understand the trouble you are having.
sending hugs and hope you can sort it out really soon.
cheers, Sharon xoxoxox
