Not completely sure what caused my stay in hospital. I had a temp of 39 and my oncologist admitted me because of this. I did feel very sick and run down, very sore throat and diahorea. When they checked my bloods, I had neutropenia (low white count) so I was put on IV antibiotics until my white cells recovered. My onc said sometimes they don't find the source of infection but the antibiotics seemed to clear things up for me.
I had the very sore nails too. My nails hung in though my thumbnails were discoloured and I lost a part of one of them after chemo finished. They soon recovered and are back to normal now.
If you feel a bit run down it is probably ok to have a day off. Your body will be working really hard to recover from each chemo. Chemo is accumalitive so you do find yourself getting a bit more tired each time. Take care. Deanne xxx
