For general body pain and fever, an over-the-counter pain reliever and fever reducer like Acetaminophen (Paracetamol) or Ibuprofen is typically recommended. Please follow the package instructions carefully and do not exceed the daily limit. Make sure to rest and drink plenty of fluids to stay hydrated. Avoid combining multiple cold or flu medications, as they may contain the same active ingredients. If your fever persists for more than three days, worsens, or is accompanied by severe symptoms like difficulty breathing, a stiff neck, or a rash, please consult a doctor immediately for a proper diagnosis.
