I got a half-inch cut on my forearm with a knife while chopping vegetables, and I have been dressing the wound myself for the last two days. What precautions should I take, and what medicines or ointments should I apply to prevent infection and heal the wound?

Keep the wound clean and dry. Wash your hands thoroughly with soap and water before changing the dressing daily. Apply a thin layer of petroleum jelly (like Vaseline) or an over-the-counter antibiotic ointment (like Polysporin) to keep it moist and prevent scarring, then cover with a sterile bandage. Watch closely for signs of infection, such as worsening redness, swelling, warmth, throbbing pain, or pus. If you develop these symptoms, or if your tetanus vaccination is not up to date (within the last 5 to 10 years), please consult a doctor. Avoid using harsh chemicals like hydrogen peroxide, which can delay healing.

I have developed a painful, pimple-like swelling on the outer ear under the tragus. A local chemist suggested Neosporin ointment and Diclogem tablets, but I have not started the tablet yet. What is the correct treatment for this condition?

A painful, pimple-like swelling under the tragus is most commonly due to a small boil, infected hair follicle, or localised skin infection in the ear area, and in most cases, it improves with simple care. You can apply a mild topical antibiotic ointment as advised and keep the area clean and dry, but avoid squeezing or pressing it, as this can worsen the infection. Warm compresses for 10-15 minutes, 3-4 times a day, can help reduce pain and swelling. For pain relief, a simple medicine like paracetamol is usually enough, and stronger painkillers like Diclogem are not always necessary unless the pain is severe. If the swelling increases, becomes redder or more painful, starts discharging pus, or if you develop a fever or spreading swelling, you should see a doctor, as you may need proper oral antibiotics or drainage.
