If you have chickenpox, it is generally safe to take paracetamol to reduce fever and relieve pain. However, nonsteroidal anti-inflammatory drugs (NSAIDs) like diclofenac should be avoided, as they can increase the risk of serious skin infections and complications during chickenpox. Supportive care, including rest, hydration, and managing itching, is important, and you should consult a healthcare professional for advice if symptoms worsen or complications develop.

If you have fluid-filled blisters on your skin that release clear fluid, do not heal, and are increasing in number, it is crucial to seek prompt medical evaluation, as this may indicate a viral, autoimmune, or other dermatological condition. Avoid scratching or bursting the blisters to prevent infection and scarring, and maintain proper hygiene while keeping the area protected. A healthcare professional can diagnose the underlying cause and provide appropriate treatment, which may include targeted therapies to control the infection or immune response, as well as supportive care to relieve symptoms. Early consultation is essential to prevent complications and ensure effective management.

While a rash, sore throat, and headache can sometimes be early symptoms of chickenpox, they are also common in other viral infections (such as measles or rubella) or allergic reactions. Therefore, a clinical evaluation by a doctor is necessary to confirm the diagnosis and guide appropriate treatment.
