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.  
Claude suggested a “hot as you can stand it” shower or bath to treat the bites. The itching will intensify for a few seconds, but then there is the relief which lasts for many hours. Some believe that the heat from the water overloads the ends of your nerves and prevent them from telling your brain to itch. Some think that the heat causes your body to release more histamine than usual and thereby less histamine around the bite. Whatever the reason, it’s commonly used as a solution to itching caused by bites.
I work @ a hotel, and just found out that one of the rooms has a bed bug problem. I work at the front desk, and never go into the rooms. But i work third shift, and sleep in the chair in the lobby. Just wanted to know what my chances were of catching them? I will be going home and looking just to make sure. But since i work here, and its un-avoidable, what are some things i can do to protect myself from taking them home?

Mechanical approaches, such as vacuuming up the insects and heat-treating or wrapping mattresses, are effective.[3][6] An hour at a temperature of 45 °C (113 °F) or over, or two hours at less than −17 °C (1 °F) kills them.[6] This may include a domestic clothes drier for fabric or a commercial steamer. Bed bugs and their eggs will die on contact when exposed to surface temperatures above 180 degrees and a steamer can reach well above 230 degrees.[31][15] A study found 100% mortality rates for bed bugs exposed to temperatures greater than 50 °C (122 °F) for more than 2 minutes. The study recommended maintaining temperatures of above 48 °C for more than 20 min to effectively kill all life stages of bed bugs, and because in practice treatment times of 6 to 8 hours are used to account for cracks and indoor clutter.[32] This method is expensive and has caused fires.[6][15] Starving them is not effective as they can survive without eating for 100 to 300 days, depending on temperature.[6] One expert recommends not trying to get rid of bed bugs exclusively on one's own.[29]

First, make sure that the suspected bugs are bedbugs, because other insects or arthropods such as a carpet beetle, scabies mite, a bat bug, louse, or other bugs may be mistaken for bedbugs. If there is confirmation of a bedbug infestation, several measures can be taken to help control or eradicate the infestation, using both nonchemical and chemical (insecticides) methods. It can take several weeks to months to achieve complete eradication of a bedbug infestation, and it may take several treatment cycles to completely eliminate them. In many cases, it will be necessary to hire a pest control service in order to implement a comprehensive extermination strategy.

However, always remember that these simply treat the problem and do not get down to the root cause. You will still need to take steps to get rid of them! Here are a couple home remedies to get rid of bed bugs that have been extremely helpful to the community. I encourage you to take a look at that article if you are serious about removing them properly.

Bed bugs typically feed at night when we are sleeping. Even though these pests commonly feed for 5 minutes, the bite itself is painless and usually goes undetected at the time. In fact, bed bugs inject an anticoagulant (a blood thinner) as they feed, which makes feeding easier for the bed bug and also less detectable to you. Although you may not see the bed bugs, or feel their bites, they know when you are around. Bed bugs are attracted to warmth and carbon dioxide. So, if you are alive, warm, and breathing - then you are broadcasting loudly and clearly to all nearby bed bugs that "dinner is served!"
One bed bug will usually take more than one bite. Once a bed bug inserts its mouthparts and finds a suitable blood vessel, it will begin feeding. However, finding the right blood vessel may take more than one injection into the skin. In addition, bed bugs are very sensitive to movement by the host they are feeding on. Therefore, if a sleeping person moves, a feeding bed bug will probably withdraw its mouthparts and begin its search for a blood meal on another part of the body. It’s important to remember that the number of bites a person receives is not indicative of the number of bed bugs that feed on that person.
