Recently I've been finding myself getting bug bites, and I'm not sure where they originate from. Usually when I notice them, it's mid-day and I'm at work. They don't tend to itch at all. I'll notice them because they are sore to the touch. They are single, raised bumps that have what feels like a hard lump beneath. I've observed two to three of them, all on my leg, and they look visually quite angry (Red, with a wide ring of redness around the raised area). I get them spaced out, not all at once. It's been about a week to a week and a half between bites. It takes quite a while for them to heal up - Even after a week and a half, I still have evidence of the first one, for example.
Notably, these are only ever single-bump bites. Not clusters or a rash.
I reached out to my doctor, who said that they look like insect bites. He recommended a thorough cleaning of my bedding, clothes, and carpet.
I examined my bedding as thoroughly as I was able, and I didn't see any evidence of bed bugs, but bed bugs have me SUPER paranoid now. I've check my sheets, pillow cases, mattress, and box spring. I haven't seen any blood, nor any shells or what look like excrement. But I've heard these little fuckers will migrate, and can sometimes be hiding in other locations. I suppose I may also be checking incorrectly?
Does anyone know the most thorough and surefire way to check for bed bugs? Does it sound likely that I may have them, or could it possibly be some other, more benign insect?
Thanks much in advance for any help.
