@Alfie, 👋 Hi,
yes, it was to prevent neuropathy. Some ( not all) chemo drugs cause neuropathy and Paclitaxel, my weekly chemo is one of them.
I was really struggling with food and my oncologist consultant nurse recommended me a BC dietitian. I saw her throughout my chemo treatment..
Have you been given arms exercises to do? Do those exercise but don’t over do. I had the same fear as you after I had my lumpectomy and lymph nodes removed. I wondered if I can lift my arm again. And yes, you can as I could. It took a while ( because I then also had cording .. my surgeon referred me to a physiotherapist).
However, now my arm has become restricted again ( cause by radiation, I finished radiation in Mar this year). My physiotherapist assured me I will be able to move my arm again😉.
