About five weeks ago bed bugs were found out work, then two weeks ago they spread, pest control has seen continuously coming to check and yesterday they gave the place the green light. I work with a largely indigent populace, the office I work at was not sprayed, during the night at some point, I will feel painful stings, hours later I have been finding small lumps or even large and hard ones, Could it be bed bugs? There is a particularly painful lump on the back of my thigh, it’s very hard too.
The significant resurgence of bedbugs in the past decade has been attributed to pesticide resistance, more frequent travel, lack of public awareness, and inadequate pest control programs. Bedbugs are obligate blood parasites (insect family Cimicidae). They can withstand a large range of temperatures but are attracted to warmth and carbon dioxide. They typically feed just before dawn. Cutaneous reactions to bedbug bites can include macules, papules, wheals, vesicles, bullae, and nodules. Bites may be confused with other skin conditions. Bedbug bite reactions are typically self-limited and resolve within one to two weeks without treatment. Bedbug infestation may cause significant psychological distress. The diagnosis of a bedbug infestation is based on history, appearance of bites, and inspection of sleeping quarters. Although there is no evidence that bedbugs transmit disease, systemic reactions may include asthma, angioedema, generalized urticaria, iron deficiency anemia, and, rarely, anaphylaxis. An integrated pest management strategy should be employed to eliminate infestation. Tactics include vacuuming, heat or cold treatment, trapping devices, and pesticides.
Spray all baseboards, loose plaster, behind bed frames and headboards, beneath beds and furniture, and bedsprings and bed frames. Do not apply to furniture surfaces or mattresses where people will be laying or sitting unless using a product labeled for that type of treatment. Infested bedding should not be treated, but should be removed, placed in sealed plastic bags, and taken for laundering and drying at high temperature.

Some patients develop blisters filled with blood or bloody fluid, especially on the arms and legs. These blood blisters are extremely rare and can burst, causing bleeding or oozing of the bloody fluid. Healthcare providers are not sure if the cause of these blisters is related to the bug or the human but have found groups of patients that were all bitten by bugs on the same train exhibiting this sign.
It’s also possible that you won’t see a reaction the first time a bedbug bites since it sometimes can take the body a while to react. (6) Some people will have an immediate reaction, while for others it could take two weeks to emerge. Your body will likely become more sensitive to bedbug bites over time, and if you get bitten repeatedly, it could be only a matter of seconds before your body shows a response.

Hi been getting bites since March. I have been to three doctors who all say the bites are not bed bug bites due to the pattern of the bites. This weekend I got bit again I have one on my leg and a two on my waistline. One of really big and the other are two small ones that are really red. I woke up in the middle of the night and saw a small bug on pillow and one on wall by bed and took a picture and from looking online looks like pic could be a bed bug or chigger. We have already checked the mattress a bunch and found no signs of bed bugs. Can I send you a pic so you can confirm what the bug might be?

Until fairly recently, most people (and even pest control professionals) had never seen a bed bug. Bed bug infestations actually used to be very common in the United States before World War II. But with improvements in hygiene, and especially the widespread use of DDT during the 1940s and ‘50s, the bed bugs all but vanished. The pests persisted, however, in some areas of the world including parts of Africa, Asia, and Eastern Europe. Over roughly the past decade, bed bugs have made a dramatic comeback in the U.S.― they’re appearing increasingly in homes, apartments, hotels, health care facilities, dormitories, shelters, schools and public transportation. Other places where bed bugs sometimes occur include movie theaters, laundries, rental furniture, and office buildings. Immigration and international travel have contributed to the resurgence of bed bugs in the U.S. Changes in modern pest control practice, less effective insecticides ― and a decrease in societal vigilance ― are other factors suspected for the recurrence. 

8 days ago my friend & i decided to crash at my grandmas house after a wild night out. in the morning we woke up in horror seeing how they freely crawled all over her mattress cover. Within the last 7 days, bite marks have been appearing all over my body, i am practically covered; as to my friend, well lucky her she has only 3 on her arm. The problem isn’t only that i have more bites than her but i believe i have an allergic reaction, the bites have massively grown in size. I do not know what else to try, Calamine doesn’t work, baking soda with water made it worse, Benadryl hasn’t done anything either. I am at a point where i am about to cry. The worst part is that in less than a month I am going on my first tropical vacation. I simply cannot handle the stress, i suffer from mild anxiety & these massive rashes have turned these 7 days into hell. I have stopped scratching because it seems to irritate the bites. Please help.
Unlike those of other insects, bed bug bites may sometimes appear in tight lines of multiple, small, red marks where multiple bed bugs have fed along an exposed area. Bed bug bites can cause itchiness. Initially, a victim may detect a slight burning sensation. The burning area then develops red bumps, known as papules or wheals (rash). In extreme cases, bites may swell dramatically or turn into blister-like skin inflammations.
