Once again, Have any of you experienced a sensation on your skin that feels like something biting? Afterward, it itches terribly and is red and swollen. This isn't the first time I've had this. In fact, nearly killed our dog and myself last year. I was sure it was fleas. After doing the dog and my house about 6 times, they convinced me it wasn't fleas, but perhaps something called a "no see'am bug" that can come in through the screen. I'm not an outdoor person, so it's hard to believe that theory. Anyway, they itch for several days and go away. Most of the marks are under my clothes and in warm places. Could it be nerves, hives, shingles? Any infor at all? No one else seems to be affected by this and Lord knows, we have a houseful of people all the time.
