Hi, I have hidradenitis suppurativa and so I occasionally have itchy or painful red bumps on my skin that can resemble acne or be as big as welts and open wounds. So recently I discovered bed bugs in my home, not an infestation but just a few. Pest control has done 1 treatment and I have encased my mattress and box spring. It has been 3 weeks since I ve seen a live bed bug but have found no dead ones from the poison. So my question is how can I tell the difference between bed bug bites and the marks from the skin condition? I need to be able to determine if I m still being bitten. Thanks!
