Painful fizzily feet

Catherine had a difficult night last night. She received her Vincristine chemotherapy yesterday and then came into our bedroom at 2am with 'fizzly painful feet'. It took quite a while for the pain to settle, and I knew it felt bad by the look on her face. The painkiller helped and she also likes a cool damp cloth to wrap her feet in (her idea) and this also seemed to help. I felt sorry for her and her little feet! The problem with Vincristine is that whilst it is a very effective drug, it causes problems with the nerve endings which mean that it can cause a pins and needles sensation and pain in the feet, particularly at night. Please pray that she has a good night tonight, and that these side effects calm down. Thankyou.
