Sometimes chemotherapy treatment can cause problems with your body's nerves. You may notice a tingling (pins-and-needles), burning sensation or weakness or numbness in your hands or feet. This is called peripheral neuropathy. You may find that you have trouble doing up buttons and opening jars, or that your legs feel numb and you have trouble walking.

As well as affecting the nerves, some chemotherapy drugs can also affect the muscles, making them weak, tired or sore. You may sometimes lose your sense of balance.

Nerve and muscle effects are frustrating, but they are usually not serious, especially if caught early. The side effects are often temporary. Let your healthcare team know if you have any symptoms of nerve or muscle symptoms. They may decide to lower your chemotherapy dose to prevent any lasting nerve damage.
