What are the symptoms of CIPN?
The symptoms or signs of chemo-induced peripheral neuropathy (CIPN) depend mostly on which nerves are involved. The most common symptoms are:
- Pain (may be there all the time or come and go, like shooting or stabbing pain)
- Tingling (“pins and needles” feeling) or electric/shock-like pain
- Loss of feeling (can be numbness or just less ability to sense pressure, touch, heat, or cold)
- Trouble using your fingers to pick up or hold things; dropping things
- Balance problems
- Trouble with tripping or stumbling while walking
- Pressure may hurt more than usual
- Temperature may hurt more than usual (mostly cold; this is called cold sensitivity)
- Shrinking muscles
- Muscle weakness
- Trouble swallowing
- Trouble passing urine
- Blood pressure changes
- Decreased or no reflexes
CIPN can cause severe pain and can affect your ability to do things like walk, write, button your shirt, or pick up coins. If it gets very bad, it can cause more serious problems like changes in your heart rate and blood pressure, dangerous falls, trouble breathing, paralysis, or organ failure.
What else can cause these symptoms?
Peripheral neuropathy can be caused by other things besides chemo, such as:
- Other cancer treatments, like surgery or radiation
- Tumors pressing on nerves
- Infections that affect the nerves
- Spinal cord injuries
- Alcohol abuse
- Low vitamin B levels
- Some autoimmune disorders
- HIV (human immunodeficiency virus) infection
- Poor circulation (peripheral vascular disease)
- The cancer itself (for instance, multiple myeloma can cause PN)
It’s very important to know what’s causing peripheral neuropathy so that the right treatment can be given. The focus here will be on peripheral neuropathy that’s a side effect of chemo – CIPN.
