Hello,
I have had an itchy left eyelid, irritation as if there is something trapped behind it for 2 days, and then last night when I got up I had an intense head ache on the left side only. I was able to gradually relax and rest, but it took about 10 minutes. Was gone when I got up, but later in the day, headache comes back again, eye is still itchy droopy eyelid. I fear that the eyes maybe because I went through a period of less going outdoors so I washed face less often, and also when I did go out twice, it was cold and windy and I didn't wear a hat, and may have picked up some dust or bug?
