headache

I remember I hardly ever have had a headache. Today after lunch, I feel felt uncomfortable, I stopped working and thinking started to wonder where, exactly, I was uncomfortable, then I found it was my forehead and it feel felt like something was pressing on it. I felt a bit of nausea. After I went back and had dinner, I had a rest for 20 minutes and I felt a bit better, It was certainly not caused by lack of sleep because i slept went to bed early last night and slept well all through the night.Maybe it was caused by catching a cold because the weather is cold and the temperature is only 11 degrees. I looked around at home and found there is a some Green Ginger wine. After I had drunk a glass of wine I feel felt more much better now.
