What should you know about internal chickenpox symptoms?

Chickenpox is caused by varicella infection. The body’s immune response can produce fever and flu-like feelings, while the skin response produces spots that become fluid-filled blisters and then crusts. Mouth or throat spots may make eating and drinking uncomfortable. Symptoms can appear in stages, so new blisters may develop while earlier ones are drying. Shingles is related to the same virus but follows a different pattern, usually affecting a limited band of skin rather than causing a widespread first infection.

Rest, drink fluids and keep fingernails short to reduce skin damage from scratching. Loose clothing and gentle bathing may help irritated skin. A pharmacist or clinician can advise whether an antihistamine is suitable for itch; do not give medicines to a child unless the label or a health professional supports the choice. Antiviral treatment may be considered for some people, especially when illness is more severe or complications are a concern. Avoid close contact with pregnant people, newborns and anyone with a weakened immune system until a clinician says the infection is no longer contagious.

Arrange prompt medical advice if breathing becomes difficult, the person is unusually drowsy, confused, dehydrated, repeatedly vomiting, or has a severe headache or stiff neck. Contact a clinician if the skin around blisters becomes increasingly red, hot, swollen or painful, or if fever persists or returns. Babies, adults, pregnant people and people with weakened immunity should seek advice early because complications can be more serious. A GP consultation can help confirm the diagnosis and choose appropriate treatment.

Could these symptoms be chickenpox or another infection? Should antiviral treatment be considered? How long should contact with vulnerable people be avoided? Which option is safest for itch, fever and discomfort?
