Yes, Imfinzi (durvalumab) is an immunotherapy that has been linked to leg cramps as a potential side effect. Leg cramps are actually a known side effect of several lung cancer treatments, including immunotherapy, chemotherapy, and targeted therapies. There are also other treatment-related reasons leg cramps can occur, such as:

- Nerve damage from chemotherapy or radiation
- Dehydration from chronic coughing or poor appetite
- Electrolyte imbalances (low potassium, magnesium, calcium, or sodium)

Here are some tips that may help manage leg cramps:

- Stay hydrated and maintain good electrolyte levels through foods like bananas (great for potassium!)
- Discuss your medications with your care team — adjusting dosage or switching treatments may help
- Apply warm or cold compresses to the affected area
- Gentle stretching exercises can provide relief
- Manage stress through deep breathing or light walks

It's really important to let your oncology team know about the leg cramps you're experiencing. They can only help if they know what's going on! If cramps last more than six hours, or your legs feel swollen or warm to the touch, seek medical advice promptly as these could be signs of something more serious like a blood clot.
