Ask your doctor about possible neuropathy due to the oxaliplatin.

Experiencing arm pain after receiving oxaliplatin is not uncommon. This chemotherapy drug can cause **peripheral neuropathy**, which is nerve damage that often leads to pain, numbness, tingling, or weakness in the extremities, including the arms (https://www.drugs.com/sfx/oxaliplatin-side-effects.html).

Here are a few suggestions to manage this pain:

1. **Consult Your Doctor**: It's important to discuss your symptoms with your healthcare provider. They may adjust your treatment plan or prescribe medications to help manage the pain.
2. **Physical Therapy**: A physical therapist can provide exercises and techniques to help alleviate pain and improve mobility.
3. **Topical Treatments**: Over-the-counter creams or patches containing capsaicin or lidocaine may provide some relief.
4. **Acupuncture**: Some patients find relief from acupuncture, which can help reduce pain and improve overall well-being.
