Ringworm is a common infection which is very contagious and can affect the scalp, body, feet, face, or nails. About 20 percent of people will have this infection at some stage of their lives.
It is caused by fungi which normally live on the hair, skin, and nails called dermatophytes.
Common symptoms of ringworm include:
- sharply defined edges, occasionally darker around the edge;
- scaly, crusted rash;
- raised, red patches which can blister or ooze;
- an itchy and unpleasant sensation on your skin.
Note – you might not know you have ringworm until the rashes appear since it has an incubation period of up to 2 weeks.
It is a common, itchy rash of the groin that is associated with a pink or red rash involving the genitals and groin folds. The rash is also caused by dermatophytes.
Symptoms of jock itch include:

Tinactin vs Lotrimin – Differences
Tinactin (tolnaftate) stops the growth of fungi which cause skin infections, such as – jock itch, athlete’s foot, and ringworm.
Lotrimin (clotrimazole) is an antifungal medication that works by disrupting the cell membrane and is part of the azole class of medications. This anti-fungal agent works effectively for the treatment of ringworm, jock itch, and athlete’s foot.
