Hi! Welcome to Health Care Magic.
A headache is usually caused by dilatation of the blood vessels in the head. A headache ca also be seen with a viral infection.
Some symptoms of a viral infection include
headaches, runny nose, weakness, and
fever. These symptoms can also be seen in a
sinus infection. Some people may also notice
nausea.
Usually, these symptoms are caused by a viral or bacterial infection.
Here are a few things one can try:
1. Drink lots of water
2. Sleep more than 8 hours a day
3. Take warm showers
4. Use a humidifier to clear the nasal sinuses
5. Gargle with warm salt water
6. Taking over the counter painkillers or antihistaminics like
Paracetamol or Cetirizine
In case the symptoms persist, it would be a good idea to get checked out.
I hope this helps. Please reach out anytime you have any questions.
