Ringworm on the arms is also referred to as tinea corporis. Contrary to the name, worms do not cause the skin condition. This common fungal infection of then skin is highly contagious. The infection, transferred from person to person or from animal to person, looks like a red ring on the skin with normal colored skin at the center of the ring. Treatment for ringworm includes using antifungal creams and controlling other factor that may cause the rash to spread or resist treatment.

Step 1

Observe the rash and visit a physician to diagnose the infection.

Step 2

Cleanse the affected area and dry thoroughly. Excess moisture increases the severity of the fungal infection.

Step 3

Decrease humidity in the house with a dehumidifier, if necessary.

Step 4

Wear loose, unrestrictive clothing over the arms. Alternatively, leave the arms uncovered.

Step 5

Purchase an over-the-counter antifungal cream at a pharmacy. Several different products are available with varying active ingredients. Tinactin, Lotrimin and Micatin are all effective in treating ringworm.

Step 6

Apply the cream to the ringworm on the arm twice daily for two to four weeks, until the rash completely disappears. If the rash remains after four weeks, see a physician.

Step 7

Watch for signs of a worsening infection or for a resistant rash. Prescription strength antifungal creams may be required to kill the ringworm. Oral antifungal medication may also be required if the condition worsens.

Step 8

Apply the medication for a few days after the rash disappears to help prevent a recurrence of the infection.

Step 9

Treat any pets—cats are especially susceptible to ringworm--that may carry the fungal infection.

Step 10

Wash and dry any clothing, bedding or other items that were in contact with the ringworm. This helps prevent a recurrence or a spread of the fungus.
