My headache got worse, so I went to the hospital.

It's not air conditioning sickness, but I started getting a headache because the cold wind started blowing.
I'm worried because I heard that coronavirus and flu are going around these days.
I went to the hospital and they said it was the early symptoms of a cold. I decided to take some medicine for a few days.

The weather has been getting colder lately. I felt like fall was coming. They say it's still hot during the day, but the mornings are quite chilly. Perhaps that's why I've been getting headaches. I personally find cold air uncomfortable, so I always wear a mask. But I think there was a problem. It was like I had air conditioning sickness, and although I didn't have a fever, my headache was so severe that I went to the hospital. Furthermore, the news has been reporting on the coronavirus and the flu quite frequently lately. I was worried, wondering if my headache was due to that. Fortunately, when I went to the hospital and received treatment, they said my headache wasn't related to the coronavirus or the flu. I'd had headaches like this before, but they didn't necessarily lead to a cold or flu. I'd thought headaches were just a natural phenomenon, but this time, they said it wasn't always like that; it was just the early stages of a cold. Since I also had a headache, they suggested I take medicine for three or four days to see if the problem persisted. Fortunately, the medicine seemed to be working, and my headache gradually subsided. Since I didn't have a runny nose or cough, I'd take the medicine until the end, but the symptoms seemed to have almost completely disappeared. There is a lot of cold wind blowing and the sun is hot at noon, so there is a big temperature difference. Everyone, please be careful of colds or flu, and if you have symptoms like this headache, it would be best to visit a hospital.
