    Does anyone have old bites that "flare up". I have bites that are several months old and at times they itch VERY badly, and some look as if they swell again but go back down. Does anyone have a reaction like mine? They sort of look like eczema patches, but every now and then "flare up".

    Okay, because I am still experiencing the most freakish case of flare-ups, I will keep responding to this question.

    The short answer is, yes, many folks have reported reactions similar to yours, and there are some comments on it in the FAQs, too, under skin reactions, I think.

    In my personal, extreme case, I am currently experiencing very visible, scary flare-ups from bites that I am so sure occurred more than 8 months ago. I am thinking this must be related to the heat for me, because my god, they look just like fresh, red clusters of bites and I keep getting more, bigger "new" (but really old) ones every day lately. Sometimes they still itch, but not so much of that now. I have to keep reminding myself of all the logical, rational, sane reasons why I am pretty sure I don't have bedbugs anymore. And I am pretty sure.

    Life is getting better for me these days, but it's like these old bites keep resurfacing to remind me not to get too cocky.

    Hi,

    Just to confirm yes bed bugs bites can flare up again even years after. I have found that there are two main situations in which this may occur:

    1 At times of high stress and low immune response - almost as if they are now part of your bodies early warning system

    2 In the presence of Bed Bugs some people who have been previously exposed will develop a bite reaction in the same location as old bites - I think this is best summarised as being some peoples early warning system of potential exposure.

    I actually have a member of staff who falls into the second category. Her role in the organisation is to screen rooms for us in hotels and similar buildings. The combination of trained eye sight, attention to detail and her automatic response make her ideal for this kind of work. Now before anyone asks yes we do pay her enough to put up with the itching and scratching that she inevitably gets from working for us.

    If you want to test yourself for this kind of response take a dead bed bug sample and place it on your skin for a few minutes, if you respond it is clearly not a fresh bite. The annoying thing is that the reaction can still take a few hours or days to develop. If you find that you get an immediate response and have 20 : 20 vision please drop me your resume.

    I thought this was an oldie but a goodie, as I am experiencing today what (I hope) are flareups of bites I rec'd a few weeks ago. Otherwise, today would be day 9 with no new bites or other signs.

    hi, my bites are now 4 months old, after about a month or so i was concerned that they were not healing so i saw a dermatologist and she did a biopsy witch confirmed i was having a reaction to bug bites, she said it would take some time but they should go away, well 4 months later i still have them in that some will disappear and look to be completely healed only to flare up again, they will itch real bad for a few days then go back down some disappearing some looking like a brown spots then a few weeks later they will flare up again, i know for a fact they are not new bites, after explaining this to my general doctor she replied that once a bug bite heals then it should not return, realizing these are the same bites i initially showed her for which she prescribed steroids that did not work then referred me to the dermatologist, she ordered extensive blood work but nothing unusual was found, at this point i can understand a bite taking a long time to heal or progressively healing but for one to be completely gone and then to re appear seems really strange, i am at a point were the doctors are not taking me seriously since they are "just bug bites" and they did try but found nothing for them to treat, my question is if after time can these become cancerous? what if any is the medical explanation for this short of stigmata (just kidding on the last part) i read the response from David but the next question is does this happen with any other insect bite, and if only with bed bugs then this potentially life long condition should be reported to the center for disease control, i don't mean to sound over the top but should not the long term cause and effect like this be studied, what other bite in nature from any animal or insect heals then re occurs ? i saw a specialist for something completely different and unrelated, this doctor is just amazing and is extremely intelligent so in conversation i actually brought this up and he is actually gonna request my file from the dermatologist even though this is nothing to do with his field he finds it very strange and something that should at least be looked at a little more seriously, i just wish there were more people like him out there i will write back if it leads to anything, thanks to all on this website especially the experts for all their help with all aspects of the bed bug issue it is helping a lot of people

    I'm on the same boat. It's been 6+ months and I also suffer from hyperpigmentation (darkened skin where I got the bites). Mine is definitely a heat-activated response. Every time I go to the gym, small round welts pop up and eventually the entire patch of darkened skin flares up.
