Mum's first chemo session

Agree with @ddon, taste buds can be affected, as can soft tissue (mouth, nose, eyes) but all recover quickly when treatment ends. Tingling in the end of the fingers and in the toes can be peripheral neuropathy, which can take longer to clear. Talk to your mother’s oncologist about how to limit this. Nausea and fatigue are the most common side effects - there is not much you can do about either - medication will be provided to assist with nausea, but some people never get it (like me). Fatigue can sometimes be hard to assess, the whole rigmarole can make anyone tired. Just rest as needed. Best wishes to you both.
