If it's not a spider, could be bed bugs. However, I've read all I could online, looked at some pictures, and so on, about bed bugs. I'm pretty sure it's not bed bugs. It's stressed that it's hard to confirm that a collection of bites are clearly from bed bugs. They warn doctors are often unable to identify them as well. Also, they're incredibly hard to find, if you have them. Two days of searching, but I've found nothing. I have a white sheet and comforter, and it says that bed bugs leave feces everywhere, and that they are distinctively black (the feces), and would show up easily if they had to crawl to get to my flesh. Also, my bed frame is white. However, there is no sign of anything. The mattress was clean, too. Also, the pictures of bed bug bites I saw looked really, bad bad. Obvious bite marks and severe redness, and a larger area of irritation. But the bites I have are puffy, and not that red. In fact, if you saw my feet two days ago, there's no way you'd know they were swollen toes if I didn't point it out to you first. Most of the bites are just under the nail, so that area would just puff up but you couldn't see the bite mark until the swelling went down a little. But the fact is that they're on my toes, and for me, any bug bite is far less severe when it's on my fingers or toes than if it were say between my fingers or on my back. The one picture I found of bed bug bites on feet looked nothing like mine; it was much worse. Of course the other problem is that some people may not have such a bad reaction to bed bug bites, so they wouldn't take pictures of their bites... Another problem is that I've read that they can itch like crazy, but mine haven't itched at all (which is how my some of my spider bites are), but they did hurt to the touch at first. It's also strange to me that only my toes have been bitten, and not any other part of my foot, or under them, or on any other part of my body exposed when I sleep. From the pictures I saw, they just bite everywhere they can. I think I've only got 8 bites total or so.
I tried to post some pics but they fucking sucked.
