Kidney disease does not usually cause mysterious skin wounds directly.
However, severe chronic itching can lead to repeated scratching, which may damage the skin.
The National Kidney Foundation notes that scratching CKD-associated pruritus can contribute to:
* Scratches
* Open sores
* Skin irritation
* Secondary infections
This is another reason persistent itching should be treated rather than ignored.
If unexplained sores appear without scratching—or wounds are not healing normally—other causes such as diabetes, circulation problems, infection, or dermatological conditions also need to be considered.
