I have red bumps that look like mosquito bites. They itch really bad and when they start to go away they leave a small like pimple. Me and my husband thought we had bed bugs but when we went to doctor yesterday she said they look like spider bites. Well we fumigate our house and still i am getting bumps. I also sweat at night can this have something to do with this? The bites are in 2-5 centermeter apart.
