Many people who go through chemotherapy experience a side effect that can linger long after treatment ends: nerve damage known as chemotherapy-induced peripheral neuropathy, or CIPN. If you or someone you love has noticed numbness, tingling, burning, or weakness in the hands and feet during or after cancer treatment, you are not alone.
What Is Chemotherapy-Induced Peripheral Neuropathy?
CIPN is nerve damage caused by certain chemotherapy drugs, particularly platinum compounds, taxanes, and vinca alkaloids. These medications fight cancer cells effectively, but they can also injure the peripheral nerves that carry signals between the brain, spinal cord, and the rest of the body.
Symptoms often start in the fingers and toes and can move inward, sometimes called a “stocking and glove” pattern. Common symptoms include:
- Numbness or tingling in the hands and feet
- A burning or shooting pain sensation
- Sensitivity to touch or temperature
- Muscle weakness or trouble with fine motor tasks
- Balance problems or difficulty walking
Why Does This Happen?
Researchers do not fully understand every mechanism behind CIPN, but it is generally linked to how chemotherapy agents affect nerve axons (the long fibers that carry nerve signals) and the small blood vessels that supply nerves with oxygen. Risk appears higher with larger cumulative doses, certain drug combinations, and pre-existing conditions such as diabetes.
For some patients, symptoms fade in the months after treatment ends. For others, CIPN becomes a long-term condition that affects daily activities like buttoning a shirt or walking without stumbling.
What Can Help?
There is no single guaranteed fix for CIPN, and every patient’s situation is different. A combination approach is often used to help manage symptoms, which may include:
- Working closely with the oncology team to review dosing and alternative regimens when appropriate
- Physical therapy and targeted exercise to support balance and circulation
- Nutritional support aimed at overall nerve health
- Non-invasive therapies that some clinics use to support nerve function and manage discomfort
Because peripheral nerves can be affected by many underlying causes, including diabetes, autoimmune conditions, and chemotherapy, a thorough evaluation matters. Our overview of peripheral neuropathy symptoms, causes, and treatment options walks through how different types of neuropathy are typically assessed, a useful starting point whether your nerve symptoms are related to cancer treatment or another cause.
When to Talk to a Provider
If you notice new or worsening numbness, tingling, pain, or balance issues during or after chemotherapy, bring it up with your oncologist as soon as possible. Early reporting can sometimes affect treatment decisions and open up more options for managing symptoms.

CIPN varies from person to person, and only a qualified healthcare provider who knows your full history and treatment plan can evaluate your symptoms and recommend an appropriate course of care.
