This pair of bed bug bite photos below show the immediate (left) and next day (right) reaction after feeding a colony of bedbugs from a container in the lab. (That's why they are contained in a small circular area).  The hive-like immediate symptoms are replace by dark red rash type reaction the following day with inflammation and less severe redness radiating out to a larger area.  
Bedbugs do, however, have a unique bite pattern. Although some bites may appear alone, most bites occur in a row of three to five bites (termed "breakfast, lunch, and dinner") or in a cluster of red bumps (a rash called bedbug dermatitis). The bites often appear in a zig-zag formation, but may appear in a straight line if the bugs bite you in the morning.
The safest and most effective approach to getting rid of bed bugs is heat treatment, in which a trained professional heats the home's rooms one by one to a temperature of 50 degrees Celsius and sustains the heat for four hours. Heat does not penetrate well into wall voids, though, so desiccant dusts are often applied to those areas. No single technique can eliminate bed bugs—combinations of approaches are essential to getting the job done.
The decline of bed bug populations in the 20th century is often credited to potent pesticides that had not previously been widely available.[44] Other contributing factors that are less frequently mentioned in news reports are increased public awareness and slum clearance programs that combined pesticide use with steam disinfection, relocation of slum dwellers to new housing, and in some cases also follow-up inspections for several months after relocated tenants moved into their new housing.[66]

I don’t get to see our kids; I can’t protect them from the little monsters; my own body is being eaten alive; the constant itching and scratching is embarrassing, as is the fact that I have bites and scars in visible places, and that my blood no longer clots properly, so if I get a paper cut, I’ll be bleeding a good half hour; we’ve sprayed, washed, dried and the bites keep coming; I’ve used prescription strength cortisode cream, Benadryl (which makes me tired and stupid at work), Zyrtec, Aveeno shower soap and even used my DOGS anti-itch shampoo. And I an still itching till they bleed, scarring, and finding new ones every day. I just…a part of me has totally lost hope that there will EVER be an escape and I’m so depressed I just want to go to sleep and not wake up
My family and I have had bed bugs for about 6-8 months we have tried everything that we could except hire an exterminator because we cannot afford it. I am actually awake right now because I just found 3 bugs in my bed!!! I have been rubbing baby oil over my whole body and have not got bit I suggest that you try it, it has helped me I can honestly say I do not get any bites when I use the baby oil
Bedbugs are obligate blood parasites that belong to the insect family Cimicidae. Cimex lectularius and Cimex hemipterus, the two bedbug species that feed primarily on humans, are oval, reddish-brown, flat, and wingless. Adults are typically 4 to 7 mm in length (Figure 1). Nymphs can be as small as 1 mm, and are translucent and lighter in color 5,7 (Figure 2). Adult females produce 200 to 500 eggs in a typical six- to 12-month life span.5,8 Bedbugs can withstand temperatures from 44.6°F to 113°F (7°C to 45°C).8
A number of vital tasks carried out during sleep help maintain good health and enable people to function at their best. Sleep needs vary from individual to individual and change throughout your life. The National Institutes of Health recommend about 7-9 hours of sleep each night for older, school-aged children, teens, and most average adults; 10-12 for preschool-aged children; and 16-18 hours for newborns. There are two stages of sleep; 1) REM sleep (rapid-eye movement), and 2) NREM sleep (non-rapid-eye movement). The side effects of lack of sleep or insomnia include:

In addition to the physical manifestations of bedbug bites, patients can experience significant psychological distress. The stigma that bedbugs are related to poor hygiene (however inaccurate) can lead to poor self-esteem, avoidance of family and friends, and suspension from work.37–39 Management of an infestation can be stressful, costly, and disruptive to everyday life. Worry can lead to insomnia, depression, anxiety, and even delusional parasitosis.37
So I have had bedbugs before and I had tons of bites everywhere from my feet to my neck! This time im not exactly sure if I have bed bugs.. I came home one evening and notices bites on my inner arm and then on my forearm, the ones on my inner arm are out of place and scattered bites, the ones on my fore arm are 3 diagonal dots. I have checked my bed and box spring seeing as I have had them before but there is nothing there? Am I being paranoid or do I really have bed bugs?
As if you needed something else to worry about, bedbugs, those pests from the old bedtime rhyme are making a comeback. More of a nuisance than a health hazard, they’re showing up to suck blood from people in hotels, college dorms, and hospitals. Take an informative look at bedbugs: what they are, where they lurk, and how to spot them before they get you.
