You can get these red-ringed patches on various parts of the body. Ringworm of the scalp, sometimes called tinea capitis , is the only form that may produce painful regions as well as spots and itchiness. If an infectious form of tinea attacks the spaces between toes or the groin region, it is indistinguishable from noninfectious athlete's foot or jock itch. Symptoms your physician may observe Your physician may want to do a culture and a microscopic exam of your skin or hair shafts to confirm the diagnosis, but skin specialists can recognize characteristic disorders at a glance. Oral drugs, such as griseofulvin, are more likely to be used if ringworm patches appear to be widespread on the skin.
Oral medication is also the effective way to treat contagious ringworm of the scalp.
For ringworm of the skin , avoid contact with infected people as much as possible. Do not share towels or clothing. If your pet seems to have a skin problem, take it to a veterinarian.
