Symptoms
By Mayo Clinic staffThe signs and symptoms of ringworm include:
- A circular rash on your skin that's red and inflamed around the edge and healthy looking in the middle
- Slightly raised expanding rings of red, scaly skin on your trunk or face
- A round, flat patch of itchy skin
More than one patch of ringworm may appear on your skin, and patches or red rings of rash may overlap. You can have tinea infection without having the common red ring of ringworm.
When to see a doctor
See your doctor if you have a rash on your skin that doesn't improve within two weeks. You may need prescription medication.
See your doctor immediately if you experience:
- Excessive redness
- Swelling
- Drainage
- Fever
