Most bites will have a small clear area in the center surrounded by redness that may or may not be raised. People tend to become more sensitive and have larger reactions after each episode. Reactions can include itch, swelling, rash and wheals (large round red area on the skin). Severe reactions can cause skin blisters and trouble breathing, although these reactions are very rare.
Hi Samantha! I highly recommend spending about 15min to investigate your bed (especially on the corners and don’t forget to look under the sheets, etc). If there are no signs of bed bugs, then I suggest that you don’t worry about it. Additionally, I have had itchy bites after a nights sleep and it turned out to be a once off occurrence, so just take action if it keeps happening. Hope that helps, sorry for the delayed response.
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.
