Back Pain After Chemotherapy: Don’t Ignore the Signs

Back pain after chemotherapy is a common concern among cancer patients. It can stem from various causes, including side effects of chemotherapy drugs, white blood cell-stimulating agents, or cancer spreading to the bones. Understanding the cause is essential to determine the right course of treatment.

Common Causes of Back Pain After Chemotherapy

1. Chemotherapy Drug Side Effects

Certain chemotherapy drugs may lead to nerve inflammation (neuropathy) or muscle pain.

2. White Blood Cell-Stimulating Agents (G-CSF)

Medications like Filgrastim or Pegfilgrastim, used to stimulate white blood cell production, can cause bone or back pain.

3. Cancer Spread to the Spine

Progressive back pain could indicate bone metastasis, which requires further imaging such as MRI or bone scan.

4. Poor Posture During Recovery

Prolonged sitting or lying in improper positions may cause muscle strain or inflammation.

Treatment Options for Back Pain After Chemotherapy

1. Pain Relievers

Start with Paracetamol for mild pain
NSAIDs or Opioids may be needed under physician supervision

2. Hot–Cold Compresses

Heat: relaxes muscles
Cold: reduces inflammation in acute pain

3. Physical Therapy

Gentle stretching and back muscle exercises
Conducted by certified physical therapists

4. Adjusting G-CSF Medications

If pain relates to G-CSF, doctors may reduce the dose or change the medication

5. Imaging When Needed

MRI or Bone Scan may be ordered to assess metastasis

When to See a Doctor Immediately

If you experience these symptoms along with back pain, you should see a doctor immediately.
