Cough, a blocked or runny nose and feverishness can occur with respiratory infections, but four days of recurring fever needs reassessment if it is continuing. An evening pattern alone does not identify the cause.
Next Steps
Record your measured temperature and arrange a physician review if fever is still present or symptoms are not improving. Rest, drink fluids regularly and avoid smoking. Bring details of any medicines already taken rather than starting an antibiotic yourself.
Health Tips
Seek urgent care for breathlessness, chest pain, coughing blood, confusion, marked weakness or inability to maintain fluids.
