From the Guidelines

Castor oil may help manage foot cysts by reducing inflammation and softening the tissue, though it's not a proven medical treatment. To try this remedy, clean the affected area, apply a small amount of castor oil directly to the cyst, cover with a bandage, and leave overnight. Repeat daily for several weeks. The ricinoleic acid in castor oil has anti-inflammatory properties that may help reduce swelling and pain. However, foot cysts often require proper medical diagnosis and treatment, especially if they're painful, growing, or interfering with walking.

Key Considerations

  • If the cyst doesn't improve after two weeks of home treatment, or if you experience increased pain, redness, or drainage, consult a healthcare provider.
  • This is particularly important for people with diabetes or circulation problems who should avoid self-treating foot conditions.
  • Professional treatment options might include drainage, corticosteroid injections, or surgical removal depending on the type and severity of the cyst.

Evidence-Based Recommendations

According to the most recent and highest quality study 1, simple cysts up to 10 cm in diameter on transvaginal ultrasonography performed by experienced ultrasonographers are likely to be benign and may be safely monitored using repeat imaging without surgical intervention, even in postmenopausal patients. However, this study is related to ovarian cysts, and its application to foot cysts is limited.

In the context of foot cysts, consulting a healthcare provider is crucial for proper diagnosis and treatment 1. They can assess the cyst and recommend the best course of action, which may include drainage, corticosteroid injections, or surgical removal.

Important Notes

  • Foot cysts can be painful and may interfere with walking or daily activities.
  • People with diabetes or circulation problems should exercise caution when treating foot cysts and consult a healthcare provider for guidance.
  • While castor oil may provide some relief, it is essential to prioritize medical diagnosis and treatment for foot cysts.
