I've been having an issue for several years and it's gotten to the point that I can't stand it anymore. My symptoms are fairly simple, but I can't figure out the cause.
I get "bug bites" on my forehead seemingly randomly. There are 2 different forms of them. The minor type is just a red, itchy spot on my forehead, usually irregular in shape, about the size of a dime or nickel, and it goes away in about an hour. The major type is usually larger, with a welt in the center just like a mosquito bite, and can last a bit longer.
In both cases, they appear out of nowhere. All of a sudden I can just feel an itchy spot on my forehead (only place I get them). The location ranges from my temple to temple, and from my eyebrows to my hairline.
What could the cause of this be? I've considered "bed bugs", but I usually get them anywhere between 3-8 hours after I get out of bed. When they occur there is clearly nothing on my head biting me, but they take the shape of a mosquito bite most of the time. I've also considered some kind of rash or allergy, but am not sure. Also, they could be stress-related, I suppose, though I've also gotten them during my most stress-free times, like watching a movie on the weekend, or during vacation on the beach.
I first noticed them when I started my job as a mail carrier 6 years ago, and they've continued almost daily (sometimes I get a 1-2 week vacation from them) since. I now work inside and still have the same symptoms.
Can anybody suggest what might be causing this?
I could post pictures if it would help. I don't have any yet, but it won't be long before I have a chance :(
Thanks in advance!
