Angular cheilitis is a common condition that causes painful cuts, cracks, redness, or irritation at the corners of the mouth. It can happen due to dryness, repeated licking of the lips, fungal or bacterial infection, nutritional deficiencies such as low vitamin B or iron levels, irritation from cosmetics, or prolonged moisture around the mouth. Since you regularly use lipstick, it is possible that certain lip products may be irritating the skin or worsening dryness, especially if the lipstick is old, expired, or used frequently without moisturising the lips. To help healing, keep the corners of the mouth clean and dry and apply a plain lip moisturiser or petroleum jelly regularly to protect the skin from cracking further. Avoid licking the lips, peeling the dry skin, or using irritating cosmetic products until the area heals. If possible, temporarily stop using lipstick for a few days and switch later to a gentle, good-quality, non-irritating product. Eating a healthy diet rich in iron and B vitamins, including green vegetables, eggs, fruits, milk, and nuts, may also help if nutritional deficiency is contributing to the problem. If the cracks are persistent, painful, associated with white coating, swelling, or not improving within 1-2 weeks, you should consult a doctor or dermatologist. They may prescribe antifungal or antibacterial cream and sometimes recommend blood tests to check for vitamin or iron deficiency. With proper care and treatment, angular cheilitis usually improves well.

Severe testicular itching is commonly caused by fungal infections (jock itch), eczema, contact dermatitis, or occasionally scabies. For immediate relief, keep the area clean and dry, and wear loose cotton underwear. You can try an over-the-counter antifungal cream like Clotrimazole or Miconazole applied twice daily. Avoid using strong hydrocortisone (steroid) creams without a doctor's advice, as they can worsen fungal infections. Because the correct treatment depends entirely on the underlying cause, I highly recommend consulting a healthcare provider or dermatologist for an accurate diagnosis and prescription if symptoms persist.

This sounds like a common, easily treatable fungal skin infection, likely ringworm (tinea corporis). To manage this, keep the area clean and dry, wear loose-fitting cotton clothing, and avoid scratching to prevent spreading. Do not share towels or clothing. For treatment, over-the-counter antifungal creams containing clotrimazole, miconazole, or terbinafine are highly effective. Apply the cream to the rash and slightly beyond its border twice daily for two to four weeks. If the rash does not improve after two weeks, continues to spread, or becomes extremely painful, please consult a healthcare professional for a proper diagnosis and potentially stronger prescription medications.

For a fungal infection on the glans (balanitis), an over-the-counter antifungal cream like Clotrimazole (1%) or Miconazole (2%) applied twice daily for 7 to 14 days is typically effective. Keep the area clean and gently dry it after washing, avoiding harsh or scented soaps. However, because this infection is recurring, it is crucial to consult a doctor or urologist. Repeated infections can be a sign of an underlying health issue, such as diabetes, or may require treating your sexual partner to prevent reinfection. Please seek a professional medical evaluation rather than repeatedly self-treating.
