Your symptoms, especially lines appearing on your skin, suggest dermographism (a type of physical hives) alongside hypersensitivity to insect bites. For relief, try an over-the-counter non-drowsy antihistamine like Cetirizine (10mg) daily. For active itchy spots and mosquito bites, apply 1% Hydrocortisone cream or Calamine lotion twice daily. To fade the dark marks (post-inflammatory hyperpigmentation), apply sunscreen daily and use creams containing Niacinamide or Vitamin C once itching subsides. Avoid scratching, which triggers the lines and dark spots. Please consult a dermatologist for a tailored treatment plan.

Ringworm that lasts for a year usually means the infection is not fully cleared, or it keeps getting reactivated. This can happen when treatment is stopped too early, cream is not applied long enough, the infection has spread to nearby areas, or there is constant sweating, tight clothing, or repeated use of steroid-mixed creams that temporarily reduce itching but allow the fungus to persist underneath. Sometimes the diagnosis also needs to be reassessed because chronic itching may overlap with other skin conditions. KZ cream can help in mild cases, but stubborn or long-standing ringworm often needs a more structured plan, sometimes including a different antifungal cream, longer duration treatment, and in some cases oral antifungal medicines prescribed by a doctor. Hygiene also plays a big role, like keeping the area dry, changing clothes regularly, avoiding sharing towels, and washing clothes in hot water if possible. Since your symptoms have been present for such a long time, it is important to get a dermatology review again. You may need an adjustment in treatment strength or duration to fully clear the infection and prevent recurrence.

Hair removal creams can sometimes make the skin a bit sensitive for a few hours because they work by breaking down hair on the surface, which can also mildly irritate the outer skin layer. Because of this, applying another active cream like KZ (ketoconazole) immediately on the same area may increase the chance of burning, redness, or irritation, especially if your skin is already sensitive or slightly scraped after hair removal. It is usually better to wait for some time and let the skin settle before applying any medicated antifungal cream. Keeping the area clean, gently washing off any residue of the hair removal cream, and avoiding friction or tight clothing can help reduce irritation. If the skin feels normal without burning or redness after a few hours, then KZ cream can be applied in a thin layer as directed. If you notice stinging, redness, itching, or peeling after applying both products close together, stop using them temporarily and allow the skin to recover. If irritation persists or worsens, a dermatologist review is important to avoid chemical dermatitis or sensitivity reactions.

Ringworm on the neck is a common fungal infection that often causes itching, redness, circular rashes, and irritation. The infection can spread more easily with sweat, moisture, close skin contact, sharing towels, wearing tight clothes, or not drying off well after bathing. If left untreated, fungal infections can slowly get bigger. To help recovery, keep the area clean and dry. Wear loose cotton clothes, try not to scratch, and avoid sharing towels, pillows, or clothing, since the infection can spread through contact. Antifungal creams like clotrimazole, luliconazole, terbinafine, or ketoconazole are often used for ringworm, but the best treatment depends on how severe and how long the infection has been present. Do not use steroid combination creams without a doctor's advice. These may reduce itching for a short time, but can make fungal infections worse later. Wash your clothes and towels often and dry them well, preferably in sunlight. Consult a doctor if the rash spreads quickly, develops pus, becomes painful, or does not get better after proper treatment, as some cases may need oral antifungal medicine.
