What happens if chickenpox is not treated?

Chickenpox causes an itchy rash that can form fluid-filled blisters before crusting. Symptoms may settle with supportive care, but untreated itching encourages scratching. Broken skin can become infected and may heal with atrophic scars, which are small depressed marks. Chickenpox can also remain dormant in nerve tissue and later reactivate as shingles. The illness can be more concerning in adults, pregnant people, newborns and anyone with a weakened immune system.

Keep the skin clean, trim fingernails and avoid picking blisters. Drink regularly, wear loose clothing and use a clinician-approved itch treatment. Avoid aspirin in children and keep away from people at higher risk until a clinician confirms the contagious period has passed. A GP consultation can clarify whether antiviral medicine or monitoring is appropriate, especially when symptoms are severe or the person is in a higher-risk group.

Seek prompt medical advice for a rash with fever that is worsening, breathing difficulty, severe headache, confusion, repeated vomiting, dehydration, or blisters that become increasingly painful, warm, swollen or filled with pus. Get urgent help for a very unwell child, an affected pregnant person, a newborn, or someone with reduced immunity. Do not wait for the rash to spread before calling.

Ask whether the illness fits chickenpox, how to control the itch safely, when the person can return to school or work, and whether vaccination should be discussed after recovery. Ask what changes in the blisters or fever would require same-day review.
