Ringworm is caused by a fungal infection. It can appear on the scalp, foot or groin area and can be very itchy. You can do several things to relieve the itching.
Use anti-fungal creams. As these treatments clear up the rash, they will reduce accompanying symptoms like itching. Over-the-counter brands include Lotrimin and Mycelex.
Apply a cold compress to the affected area. Use a cool, damp towel or wrap an ice pack or package of frozen vegetables in a cloth. Cooling the area will relieve the itchy feeling.
Use anti-itch medicines. These include calamine lotion or over-the-counter hydrocortisone cream. If itching is severe, you can use over-the-counter oral antihistamines like Benadryl to relieve the itch.
Soak the affected area in water mixed with oatmeal or baking soda for as long as desired.
Keep the affected area clean and dry. Moisture aggravates itching.
