Neuropathy

• Neuropathy refers to persistent sensations of localised numbness, prickling/tingling, hot/cold or itching/burning.
• It may also come together with pain. Damage of one or more sensory nerves that carry messages to the brain causes neuropathies. Affected body parts may become sensitive and feel dull. The function of the body parts involved may be affected. 

Neuropathies happen when:  

• nerve damage caused by pressure, chemicals or penetrating injury, making it malfunction. 
• growth of tumor in advanced cancer patients which compress against the nerves around lymph nodes.
• peripheral nerves in hands and feet are damaged by cancer chemotherapy. 

Although it takes months for the peripheral nerves to grow, it will recover eventually.  

The extremities of the arms and legs are usually affected: 

• Feet/toes – because of the less sensitive sensation, patients may lose balance and steadiness when standing. This will increase the risk of falls. 
• Hands/fingers – decreased dexterity in fingers movement, such as fastening buttons and writing. 
• More commonly,  
  • Difficulty in judging temperature, risk of burns. 
  • Experience different uncomfortable sensations such as burning, stinging, itching, vibrating or tingling sensations, hindering daily activities. 
• The discomfort is distressing and may cause a person to feel more tired and lead to depression, especially normal daily activities are interrupted. 

1. What you need to know about neuropathies

• Neuropathies can take a long time to heal. 
• Although neuropathies can’t be “switch off”, medication can help to manage severe pain. In most cases, neuropathies can be resolved within 1-2 years. 
• The brain will gradually adjust to the damaged nerve input, “tuning out” the disturbing sensations into “background” or invisible sensations. 
• Try to accept the neuropathy as temporary situation and continue with your life as normally as you can.  

2. Keep an active lifestyle

• Do regular exercise, as this helps heal the body, promoting nerve growth and regeneration. 
• Have a regular and good sleep pattern. Tiredness can intensify neuropathies, making it more difficult to ignore. 
• Eat a healthy, mostly vegetable-based diet including tofu, beans, legumes and consume less animal protein.  
• Minimise psychological stress and try to keep positive. Be patient and avoid being too pessimistic when dealing with problems. 

3. Temperature

• Avoid extreme temperature (too hot or cold), as this may affect blood flow which can alter sensation and risk burns.  
• Try applying warm and cool packs on the affected area to see if they offer any relief.

4. Massage

• Massaging the affected area may help to improve circulation and help stimulate both muscle and nerve growth. 
• Keep using the affected limb, even you feel discomfort, as much as possible to prevent muscle loss. 

5. Safety

• If you have severe loss of sensation in hands or feet, wear gloves and thick socks/ slippers/ indoor shoes around the house to help protect against injury.  
• Pre-setting the water heater temperature to less than 48 °C, or asking a family member to test the water temperature before taking shower or washing dishes can prevent getting burnt. 
• Be especially vigilant when cooking and using sharp objects, to avoid burns or cuts.  
• Do not drive if you cannot sense the foot pedals. 
• Avoid working at heights or using a steps/ladder, especially if you experience loss of sensation in your legs/feet, or have balance difficulties. 
• Ensure good lighting at night and be careful of tripping. 

6. Psychological responses

• Neuropathies can be distressing. Affected people can feel down or become depressed. If you are experiencing depression, don’t hesitate to seek help from your oncologist, family or friends. Professional counselors always are good to talk with and can provide professional advice.
