Bug Bites, Insect Bites, or Skin Welts

While I slept, I felt an itching. When I woke up I noticed two welts on my neck on separate sides. Are these bug bites or skin flare ups?

People that have dermographism often wake up with welts. Many individuals experience more itch during the night than during the day. The itching, often intense but sometimes mild, causes people to scratch the itch while sleeping or in a state of drowsiness. Of course, with dermatographism the scratching will cause skin welts.

Also, the pressure applied to the skin while sleeping may also cause welts to develop.

Without seeing the welts it is difficult to say that they are bug bites or insect bites. Welts caused by dermatographism general subside after about 30 minutes. Bug bites would likely show for much longer than that. More information on bug bites at insect bite treatment page.
