Bite marks on body
Some people are allergic to the salivary gland injection made by a bed bug and thus show "mosquito" like welts on their body where the insect has fed.
No visible bite marks on body
Not everyone is allergic to the bed bug salivary gland excretion, therefore, one person may show signs while a partner sleeping in the same bed at the same time shows no signs on their body, when in fact the bug has fed on them too.

Bed bugs are not really dangerous to eat as they are really tiny. They can however make you feel a bit sick if you do.
Usually not, but sometimes the bitewound gets infected. That may result in various skin infections, from pimple-like to furuncle-like.
Bed bugs are harmless for the most part. They often invoke feelings of disgust, but they are unable to transmit diseases to humans. If an infestation is severe, a bug exterminator can be called in for assistance.
This is extremely unlikely.However, if you are severely allergic to bed bug bites, a bite can result in anaphylaxis which is breathing difficulties, low blood pressure, and eventually shock if untreated.
Hey - bed bug bites tend to be on upperbody and flies lower body
No, bed bug bites are not contagious and bed bugs are not known to transmit any diseases to people. However bed bugs themselves can be transmitted from one person's clothes to another's bed and then bite that person.
It Can Be In Both
There are many ways to hide bed bug bites. You can cover them up with clothing. You could also use concealer or cosmetic makeup to assist in covering up the bites.
If you don't have bedbugs your bites are not from bedbugs, or you are being bitten while you are somewhere else. Bedbug bites are commonly confused with flea bites and mosquito bites. There is also a skin rash called Pityriasis Rosea that may be caused by a virus and that may look like Bed Bug bites at first. If you think you have a Bedbug bite go to a doctor, have a specialist inspect your home for bedbugs, or research about what Bedbug bites look like. Bedbugs are not known to transmit diseases or parasites to people, but their bits can be painful and worrisome.
