When to See a Doctor
While many causes of itchy legs are minor and treatable at home, persistent or severe itching, especially accompanied by other symptoms, warrants medical attention. Consult a doctor if:
- The itch is severe and doesn't respond to home remedies.
- You have other symptoms, such as swelling, redness, or skin changes.
- The itching is accompanied by pain or discomfort.
- You have a history of medical conditions, such as diabetes or venous disease.
