Chemotherapy-Induced Peripheral Neuropathy (CIPN) - Asymmetrical Patterns

Thank you for sharing this. What you're describing—where neuropathy affects one side more than the other—is actually not uncommon, though it's worth discussing with your care team.

What We Know About CIPN Patterns

Asymmetrical neuropathy (uneven side-to-side) can occur for several reasons:

• Individual variation: People respond differently to chemotherapy. Some patients naturally develop more nerve damage on one side
• Cumulative exposure: If you had any localized treatment (like a port on one side, or regional therapy), that area might be more affected
• Pre-existing factors: Previous injuries, nerve compression, or other conditions on one side can make that area more vulnerable to chemo-related damage
• Natural recovery variation: As nerves heal, they often do so at different rates on each side

According to the American Cancer Society and NCCN Guidelines on Cancer-Related Neuropathy, CIPN typically affects the hands and feet symmetrically (both sides equally), but asymmetrical presentations do occur and aren't necessarily a sign of something wrong.

Important Questions for Your Oncology Team

Since you're noticing this pattern, ask your doctor:

1. "Is the asymmetrical pattern (right foot worse than left) typical for my type of neuropathy, or does it warrant further evaluation?"
2. "Could this be related to something other than chemotherapy, like nerve compression or a previous injury?"
3. "Are there specific treatments or interventions that work better for localized neuropathy like this?"
4. "Should I see a neurologist to rule out other causes?"

What Might Help

While your doctor evaluates this:

• Document which areas are numb and any changes you notice
• Note if the pattern is worsening, stable, or improving
• Keep track of any pain, tingling, or other sensations
