A dry cough along with severe headache and mild fever is commonly seen in viral infections such as the common cold, flu, or throat infections, although allergies, sinus infection, or irritation of the airways can also cause similar symptoms. In many mild cases, the condition improves gradually within a few days with rest and supportive care. Drinking plenty of warm fluids, taking steam inhalation, doing warm salt-water gargles, and getting adequate sleep may help soothe the throat and reduce cough irritation. Warm soups, herbal tea, and honey with warm water may also provide relief for a dry cough in adults and older children. For headache, fever, and body discomfort, paracetamol may help when taken in the proper recommended dose. Avoid smoking, cold drinks, dust exposure, and staying awake late at night, as these may worsen symptoms. Antibiotics are usually not needed unless a doctor suspects a bacterial infection. If the headache becomes very severe, fever increases, breathing becomes difficult, chest pain develops, or the cough lasts more than 1?2 weeks, you should consult a doctor for proper evaluation. Medical attention is also important if you feel extreme weakness, vomiting, confusion, wheezing, or a persistent high fever. With proper care, hydration, and rest, most viral cough and fever illnesses improve gradually without complications.
