Are bedbug bites dangerous

For most people they are just an extremely irritating annoyance rather than a danger. But because bedbugs inject both a anaesthetic and a coagulant into everybody before they suck the person's blood and while the person is usually in a deep sleep, one danger is that when the anaesthetic effect wears off the itch can feel so irritating that the person may scratch where the wound in their limb is frantically to get relief either while still asleep or after waking. Scratching a wound particularly if the person's finger nails are not clean could inject dirt into the bloodstream. Also about one person in five is apparently allergic to the substances the bedbug injects into them and this can cause more dangerous side effects such as swelling, chronic or acute rashes or in rare cases broncho-spasm or anaphylactic shock. Also if a bed is very heavily infested so the sleeper is bitten by a large number of bedbugs while asleep successively over a prolonged period, anaemia can occasionally be caused, which can lead to fatigues and headaches and in very isolated cases breathlessness and pain in the centre of the chest. But such instances are the exception not the rule.
