For the past few years, all mosquito bites on my legs turn red and blotchy. Like fire engine red with an irregular, jagged border. Plus, it takes weeks for the redness to go away. This doesn't happen with mosquito bites anywhere else on my body- only on my legs. I'm pretty fair, so they really stand out. They make me self-conscious because it looks like I have chicken pox! Any ideas what the problem could be? I should note that this started happening around the same time I developed seasonal allergies when I moved to VA. Do you think there could be a connection?
