- Lotrisone should not be used longer than 4 weeks for treatment of tinea pedis. If there is no clinical improvement after 2 weeks of treatment, the diagnosis should be reviewed.

Jock itch is an itchy red rash that appears in the groin area. The rash may be caused by a bacterial or fungal infection. People with diabetes and those who are obese are more susceptible to developing jock itch. Antifungal shampoos, creams, and pills may be needed to treat fungal jock itch. Bacterial jock itch may be treated with antibacterial soaps and topical and oral antibiotics.
The term "ringworm" or "ringworms" refers to fungal infections that are on the surface of the skin. A physical examination of the affected skin, evaluation of skin scrapings under the microscope, and culture tests can help doctors make the appropriate distinctions. A proper diagnosis is essential to successful treatment. Among the different types of ringworm are the following: tinea barbae, tinea capitis, tinea corporis, tinea cruris, tinea faciei, tinea manus, tinea pedis, and tinea unguium.
Fungal nails (onychomycosis) may be caused by many species of fungi, but the most common is Trichophyton rubrum. Distal subungal onychomycosis starts as a discolored area at the nail's corner and slowly spread toward the cuticle. In proximal subungal onychomycosis, the infection starts at the cuticle and spreads toward the nail tip. Yeast onychomycosis is caused by Candida and may be the most common cause of fungal fingernail.
Athlete's foot (tinea pedis) is a skin infection caused by the ringworm fungus. Symptoms include itching, burning, cracking, peeling, and bleeding feet. Treatment involves keeping the feet dry and clean, wearing shoes that can breathe, and using medicated powders to keep your feet dry.
Balanitis (Inflammation of the Head of the Penis)
Balanitis is a condition in which the skin of the head of the penis becomes inflamed. If the foreskin is also inflamed, it is referred to as balanoposthitis. Balanitis usually occurs in uncircumcised males with symptoms of pain, swelling, and redness at the head of the penis. Often, balanitis is caused by poor hygiene or some medical conditions such as diabetes, and yeast infections. Treatment for balanitis is directed at the cause of the condition and may include creams or other medications.Balanitis is not an STD; however, it may have similar symptoms.
Is Balanitis Contagious?
Balanitis is a condition in which the head of the penis and/or foreskin that surrounds the head of an uncircumcised penis becomes inflamed. Balanitis is contagious if it is caused by certain bacteria, fungi, or viruses. Risk factors for balanitis are congestive heart failure, cirrhosis, morbid obesity, poor personal hygiene, diabetes, and sexually transmitted diseases (STDs). Signs and symptoms of balanitis are itching, swelling, redness, and tenderness around the head of the penis and the surrounding foreskin.
Is Jock Itch (Tinea Cruris) Contagious?
Jock itch is a fungal infection in the groin area that causes a raised, itchy, red rash. Jock itch can typically be treated with antifungal medications. People may need to seek medical care for jock itch if the groin area becomes swollen, tender, if red streaks appear, or if the lymph nodes become swollen.
