I just discovered the cause of my skin reaction this morning. Been spending a lot of time at a friends place and started to get red spots that were intense and itch. It just got worse and worse. The dermatologist did a biopsy and found no bacteria or virus. Skin scrapping found no fungus. It was a matter of finding out what was causing my skin to become so swollen I couldn’t see some of the bite marks. It only affected my legs, feet, arms, upper back, chest, neck, and shoulders. No midsection bites.
If you are experiencing itching, burning, and other forms of pain, there are a couple of treatment methods you could try. The most common recommendation is a topical corticosteroid cream or an anesthetic, which are applied directly to the wound and rubbed in to provide relief from the itching. A possible alternative to corticosteroids is calamine cream, though the FDA isn’t convinced of its effectiveness.

I have a situation were I have been infested in my room,I have been beaten and I have red spots all over my body, is itching at night and affected my sleeping time, I spoke to the landlord to get a treatment but they dont seem to care much, should I move to a diferent place? What do I need to do in order not to be follow into the new place? Any recomendation out there?
Bed bugs usually bite people at night while they are sleeping. Hungry bed bugs may also feed during the daytime, especially if this is when the occupant normally sleeps. They feed by piercing the skin with an elongated beak through which they withdraw blood. Engorgement of the bed bug takes roughly three to 10 minutes, but because the bite is painless, the person seldom realizes they are being bitten. Bed bugs normally do not reside on people like head or body lice do; instead, immediately after feeding, bed bugs crawl to a secluded location to digest their meal. Symptoms after being bitten by bed bugs vary from person to person. Many develop an itchy red welt within a day or so of the bite. Others have little or no reaction. Sometimes the reaction is delayed days or even weeks after the actual bite occurs, which can make it difficult to determine where or when bites actually occurred. Studies conducted in bed bug-infested apartments suggest about 30 percent of people do not react even when bitten repeatedly over time, and there is still higher incidence of non-reactivity among the elderly. Unlike flea bites, which occur mainly around the lower legs and ankles, bed bugs feed on any skin exposed while sleeping (face, neck, shoulders, back, arms, legs, etc.). The welts and itching are often wrongly attributed to other causes, such as mosquitoes. For these reasons, infestations may go a long time unnoticed, and can become quite large before being detected. 

I am apparently allergic to these things. My bites swell to huge sizes and I get red marks running up my arms and it itches like crazy, almost like a burning itch. However, doing some research I found an effective way to stop the itch. Its not for everyone, but for someone like me who can’t even touch the shells (my fingers have gotten swollen searching for the damn things), this works for me. Again, not for everyone:
There are thousands of types of spiders (technically arachnids and not insects) crawling around the U.S., but only two of them–the black widow and the brown recluse–can cause serious problems, and even those are rare. Most of the time you’ll see red bumps that hurt and itch if you’re bitten by a spider. Very few people get the severe pain and cramping of a widow bite or the decaying ulcers of a recluse bite (although if you do, get medical help right away).
As for traps, these capture methods may not be full-proof for all bedbug species. Researchers have found that while both the common and tropical bedbug species have hairy feet, C. hemipterushas denser foot hairs, making this tropical insect an expert climber on slick surfaces. In the study, detailed on March 15, 2017, in the Journal of Economic Entomology, the researchers found that adult tropical bedbugs were much better at escaping traditional pitfall traps, which held onto most of the common bedbugs in the study.
Bed bug bites can leave you with painful inflammation and since they love to hide in beds, you may be bitten a number of times before you wake up in the morning! If you have a severe allergic reaction, its recommended that you seek professional medical assistance as soon as possible. Besides medical creams and pills, things like tea tree oil, baking soda and even lemon juice can also give you relief at minimal cost. I highly recommend that you try these first as they work really well.
Treatment is symptomatic.[2] Eliminating bed bugs from the home is often difficult.[2] Part of this is because bed bugs can live for a year between feeding.[2] Repeated treatments of a home may be required.[2] These treatments may include heating the room to 50 °C (122 °F) for more than 90 minutes, frequent vacuuming, washing clothing at high temperatures, and the use of various pesticides.[2]
Blood spots found on one’s sheets, bites and the presence of bed bug feces and cast skins are some of the indications of a bed bug infestation. Bites are commonly found on the parts of the body that are more likely to be exposed to bed bugs during sleep – the hands, neck, face, shoulders, legs and arms. While not always the case, bed bug bites are often grouped together in a small area and at times may occur in a line or a zigzag pattern. Bites normally look like small, flat or raised areas that may become inflamed, itchy, red or blistered. Bed bug bite reactions don’t always appear immediately after you’re bitten and may take a few days to begin causing symptoms. However, not everyone reacts to bed bug bites in the same manner.
