I have been getting these welts all over for the last 6 months and my doctors do not know what could be causing it. I did have an exterminator come out and look for bed bugs and they said they didn't see any sign of them. But I am going crazy trying to figure out what is causing this. Most pictures I see of bed bugs do not look this swollen, but I might be having an allergic reaction? The part that gets me is sometimes they are in a row and if it was just hives I feel like it wouldn't do that. Did anyone else have this problem when they had bed bugs? I have never had allergies in my life, so it seems weird to just have hives all of a sudden after 30 years.
