Hi Kay
Sorry to hear that your mum is feeling so unwell.
You don’t say what type of chemo your mum is on. There are lots of different drug combinations and dosages, so the effects can vary quite a bit from one person to another.
The best advice is always to speak to the doctors or nurses at the hospital or the Myeloma UK helpline, they are the experts. This is what they are there for. There may be other options which you could discuss with the medical team.
In my case, I was on CTD for six cycles. Managed quite well for the first two and then started to notice side effects, but not the ones you mention.
Hope this helps.
David
