Chickenpox is usually a viral illness that settles on its own, so treatment mainly focuses on relieving symptoms and preventing complications. You can take Paracetamol for fever and body aches, and apply calamine lotion to reduce itching; in some cases, a doctor may prescribe an antihistamine for severe itching. Keep yourself well hydrated, eat light, nutritious food, take adequate rest, and avoid scratching the blisters to prevent infection and scarring; keep nails short and wear loose clothing. Maintain good hygiene and stay isolated until all blisters dry and form scabs to avoid spreading the infection. In certain cases (like adults, severe symptoms, or high-risk patients), a doctor may prescribe antiviral medicines, so consult your doctor if symptoms are severe, persistent, or if you develop complications like high fever or breathing difficulty.
