Can bed bug bites go away during the day?

AnswerFor fast relief from the bites, you are advised to run it under lukewarm running water for approximately a minute, which will minimize the inflammation and take your mind off it.

For other treatment of the bites, you should take some antihistamine or visit your local pharmacy to obtain a suitable cream that will help reduce swelling and relieves the itching.
