A cough lasting 4 days with nighttime throat pain may be due to throat inflammation or infection. Crocin helps reduce fever and pain but does not directly treat cough. Warm fluids, steam inhalation, and adequate rest can help soothe the throat and reduce coughing. Consult a doctor to identify the cause and recommend appropriate treatment if symptoms continue.

Headaches and tiredness can happen for many reasons, such as dehydration, stress, lack of sleep, vitamin deficiencies, or anaemia. It is important to consult a doctor for a proper evaluation before taking any medication. Until then, get adequate rest, stay well-hydrated, and eat a balanced diet.
