Paracetamol is effective in reducing pain and fever.
It is indicated for the symptomatic relief of occasional mild or moderate pain, such as headache, dental pain, muscle pain (contractures) or back pain (lumbago), as well as febrile states in adults and children weighing more than 33 or 42 kg (10 - 12 years, approximately).
You should see a doctor if the fever worsens or does not improve after 3 days and the pain after 5 days.
