What is peripheral neuropathy?

Peripheral neuropathy is a kind of nerve damage that typically affects the extremeties as feet and legs and sometimes it affects the hands and arms.

This is avery common type of neuropathy. Up to 50% of people with diabetes have peripheral neuropathy.

Symptoms of peripheral neuropathy.

If you are suffering from peripheral neuropathy, you may experience some signs in feet, legs, hands, or arms as:

  • burning sensation
  • tingling, like “needles or pins”
  • numbness
  • pain
  • weakness
  • You may experience extreme pain in your feet, legs, hands, and / or arms, even if they are touched lightly. You may also feel sensing pain or temperature in these parts of your body.

Problems caused by peripheral neuropathy.

Peripheral neuropathy can cause foot blisters and sores. If peripheral neuropathy affects feeling in your feet, you may not notice pressure or injuries that lead to blisters and sores. Diabetes can delay the healing of these wounds and increase the chance of developing infections. These infections and sores can lead to the loss of a toe, foot, or part of the leg. Treating foot problems early can lower the chances of developing serious infections.

This type of diabetes-related nerve damage may also lead to changes to the shape of your feet and toes. Some people with diabetes may suffer from rare condition which is Charcot’s foot, in which the bones and tissue in the foot are damaged.

Peripheral neuropathy can make you more likely to feel unbalanced and fall, which can increase the chance of fractures and other injuries. The peripheral neuropathy chronic pain can also lead to grief, anxiety, and depression.

  • putting a tuning fork against your great toes and higher on your feet to check if you can feel vibration
  • nylon strand touching to each foot and some toes to test if you can feel it this procedure is called a monofilament test
  • reviewing the patterns you make when you walk
  • testing your balance
  • checking temperature changes feelings in your feet.

Diagnosis of peripheral neuropathy.

A blood test to check for thyroid problems, or kidney disease, or low vitamin B12 .
