Peripheral neuropathy (PN) is caused by damage to the nerves that carry information from your brain to the other parts of your body and back again. It may be a side effect of chemotherapy drugs, a late effect of radiation therapy, or a symptom of myeloma.
Signs and Symptoms of Peripheral Neuropathy
Signs and symptoms of PN may include:
- Numbness, pain, tingling, burning or "pins and needles" sensation, especially in your fingers or toes
- Difficulty hearing or ringing in your ears
- Changes in vision
- Difficulty picking up objects or performing tasks such as buttoning your shirt or picking up a coin
- Constipation or difficulty controlling your bowels or bladder
It is very important to let your healthcare provider know if you are experiencing any of these symptoms. While PN often can't be prevented, it is possible to keep it from getting worse.
Managing Peripheral Neuropathy
If you are experiencing weakness or decreased sensation as a result of PN, you may be at risk for tripping or injury. Here are some tips to help you cope with PN:
- Ensure that floors and stairs are clear of objects or spills
- Take care on snow and ice
- Have a pair of mittens by the freezer to prevent burns when taking items out
- Always use oven mitts while cooking
- Turn your water heater down to prevent burns in the dishwater or shower
- Take care when using sharp objects such as knives and scissors
- Ensure handrails are secure along stairs
- Install rails in the shower or tub, and by the toilet to prevent falls
- Avoid using the good china!
How Long Will It Last?
In many cases, the symptoms of PN will go away after treatment is completed. It may take months or years to get full sensation and control back. In other cases the PN may be permanent.
The Bottom Line
PN can be a challenging side effect for patients. There is a feeling of loss of control when you have a side effect that you can not prevent and have difficulty treating. The most important thing to do is let your healthcare provider know as soon as you begin to experience symptoms of PN, and take steps to avoid injury in the meantime.
