For a wet cough with nasal blockage and head pain, try steam inhalation or a cool-mist humidifier, use saline nasal drops, drink plenty of fluids, and get enough rest. You can take paracetamol for pain or fever if needed. If symptoms persist or worsen, consult a doctor.

If you have a severe cold with frequent sneezing and nose pain, try steam inhalation and use saline nasal drops or spray to soothe irritation. Rest well, drink warm fluids, and avoid cold air or dust. If symptoms last more than a few days, consult a doctor for proper treatment.

Allergy symptoms all over the body can be managed with anti-allergy medicines, but the right medicine depends on the cause and severity. It is better to consult a doctor who can suggest a suitable option and the correct dose. Avoid things that trigger your allergy and keep your skin well moisturised. Do not take medicines repeatedly without proper advice.

If you have back acne along with itching, azithromycin and levocetirizine can help temporarily, but you may need a better long-term routine. Use a body wash while bathing, avoid very tight clothing, and shower after sweating. For itching, moisturising the skin and avoiding harsh soaps also helps. If the condition persists or worsens, consult a dermatologist. Azithromycin should not be taken repeatedly without medical advice, as it may cause antibiotic resistance.

Red, itchy skin on your neck may be a fungal infection that has not improved because it needs proper antifungal treatment. Keep the area clean and dry, avoid scratching, wear loose clothing, and consult a dermatologist to get the right medicine and prevent it from coming back.
