Developing a rash after a fever is quite common and is often a harmless response to a viral infection or a reaction to fever medication. To relieve the itching, you can take an over-the-counter antihistamine like cetirizine or loratadine. Applying calamine lotion or taking cool baths can also soothe your skin. Avoid hot water and scratching. Please consult a doctor to help identify the exact cause. Seek immediate medical attention if you experience any urgent symptoms like difficulty breathing, swelling of your face or throat, or if the rash begins to blister.

Your symptoms suggest an allergic reaction, possibly triggered by dust or another environmental allergen. Itching of the hands and face, along with facial swelling, may occur in conditions such as allergic dermatitis, urticaria, or dust allergy. Antihistamines, such as loratidine, cetrizine, or fexofenadine, are commonly used to reduce itching and swelling, but should be taken as advised by a doctor. It is also important to reduce exposure to dust by keeping rooms clean, washing bedsheets regularly, wearing masks while cleaning, and avoiding known triggers. Applying a gentle moisturiser may help if the skin is dry or irritated. However, facial swelling should not be ignored, especially if it becomes severe or is associated with difficulty breathing, wheezing, throat tightness, or dizziness. These can be signs of a serious allergic reaction needing urgent medical attention. Avoid scratching the skin, as this can worsen irritation and lead to infection. If symptoms keep returning, a doctor may recommend allergy testing or further treatment depending on the exact cause.

Allergic rhinitis (hay fever) and sinus problems commonly cause symptoms such as a runny nose, sneezing, nasal blockage, itching, and headache or facial pressure. These symptoms are often triggered by dust, pollen, smoke, weather changes, or other allergens. Medicines called antihistamines, such as cetirizine, levocetirizine, loratadine, or fexofenadine, are commonly used to reduce sneezing and a runny nose. Nasal steroid sprays may also be prescribed by a doctor to reduce inflammation inside the nose and provide better long-term control. Saline nasal rinses or steam inhalation can help clear mucus and reduce congestion naturally. It is important to avoid triggers as much as possible. Keeping the house dust-free, wearing masks in dusty areas, and avoiding smoke exposure may help reduce symptoms. Drinking enough fluids and getting proper rest can also improve recovery. Do not use nasal decongestant drops continuously for many days without medical advice, as they may worsen blockage over time. If you develop fever, severe facial pain, thick yellow or green mucus, or symptoms lasting for many weeks, you should consult an ENT doctor for proper evaluation and treatment.

The recurring nature of your body-wide allergy suggests that the underlying trigger may not have been identified or that the inflammation may require a longer course of treatment. Please consult your doctor or dermatologist for allergy testing and a long-term management plan rather than relying on short-term relief from medications.

You can manage excessive itching and skin allergies by avoiding known irritants and hot showers, applying fragrance-free moisturisers or calamine lotion, and taking over-the-counter antihistamines. If symptoms persist or worsen, please consult your doctor or dermatologist for proper diagnosis and treatment.
