Headache from direct fan. Old problem!

There isn't sufficient information to reach a specific diagnosis. From the given history it is likely to be sinusitis. Sinusitis is a common inflammation of the paranasal sinuses, the cavities that produce the mucus necessary for the nasal passages to work effectively. It can be acute or chronic, and it can be caused by viruses, bacteria, fungi, allergies, or even an autoimmune reaction. Although uncomfortable and painful, sinusitis often goes away without medical intervention. However, if symptoms last more than 7 to 10 days, or if there is a fever or a bad headache, you will require medical intervention. These steps may help: - Do steam inhalation(plain steam) regularly - Drink water at an average of 3 liters per day - Avoid caffeinated and alcoholic beverages as they cause dehydration and will worsen your condition. - Have spicy food once in a while which will help clear your sinuses - Use a humidifier in your room which is seen to be beneficial in sinusitis - Wiping the face regularly with a towel moist with hot water has also shown to help. If the condition persists or worsens kindly visit the ENT at the earliest.

Follow the steps as advised
