For your symptoms, you can take paracetamol to help relieve body tiredness and aches. For the cold and runny nose, an over-the-counter antihistamine like cetirizine or loratadine can provide relief. If you have a dry cough, a cough suppressant containing dextromethorphan may help. Most importantly, get plenty of rest and stay well-hydrated with warm fluids. These symptoms are very common and usually resolve with rest. However, please consult a doctor or pharmacist to ensure these generic medicines are safe for you, and seek medical attention if your symptoms worsen or you develop difficulty breathing.

It is important to clarify if this is an allergic reaction or a true skin infection, as they require completely different treatments. Applying steroid creams (common for allergies) can actually worsen a bacterial or fungal infection. For temporary relief from itching, you may take an over-the-counter oral antihistamine like Cetirizine or Loratadine. Wash the area gently with a mild cleanser and avoid picking at the bumps. I strongly recommend consulting a doctor or dermatologist for an accurate diagnosis so they can prescribe the correct medication, such as a topical antibiotic cream for an infection or a specific steroid cream for an allergy.

Spreading itchiness can be caused by a mild allergic reaction, contact dermatitis, or dry skin. To find relief, you can take an over-the-counter oral antihistamine like cetirizine or loratadine. For the body, applying a soothing calamine lotion or a mild generic 1% hydrocortisone cream can help. Be very cautious with your face; apply only a thin layer of mild hydrocortisone for a couple of days, or use a gentle, fragrance-free moisturizer. Please avoid scratching to prevent irritation. If you notice any pain, blisters, or if the itching persists, it is best to see a doctor for a personalized evaluation.
