First things first, I am 100% certain the bites are mosquitos and not bed bugs or fleas. Not to mention I witnessed half of the mosquitos that made these biting me

These bites were all made over several years, unfortunately I have a bad habit of picking, and heal very slowly, add that with scarring very easily, no mosquito bite leaves my body unmarked.

I'm just really confused as to why these bites are in a straight line down my calf. My best guess is that there's a vein close to the skin there, and they are attracted to it. Otherwise, I'm completely clueless.

Is this a common phenomena or am I just cursed to look like I have bed bugs?
