Epidermal bumps, such as epidermoid cysts, are common benign skin growths. In homeopathy, treatment is individualized based on a person's overall health and specific symptoms. Some homeopathic remedies that practitioners might consider for skin lumps include Silicea, Hepar sulphuris, and Calcarea carbonica, among others.
Next Steps
I recommend consulting a licensed homeopathic practitioner who can assess your specific situation and provide guidance tailored to your needs.
