How do you know it's a "bite"? Could it be a small rash that keeps getting scratched open? Or perhaps a wound in a place on your leg that gets a lot of movement, or rubs against clothing, or something else that delays healing? In 6+ years, why haven't you mentioned this to your doctor? 

It seems odd that the tissue hasn't healed completely in all that time, even if you were interrupting the process somehow. After hemostasis, there's a step where the wound is cleansed by fluids and coagulating platelets before the real repairs can begin. It sounds like your wound is stuck in that phase somehow. We can talk about what it might be, but we can't advise you what to do about it, other than ask your doctor. I hope that makes sense.

Yes see your doctor.

 

There are some parasites which lay eggs that hatch and burrow out to lay more eggs that hatch and burrow............

Thus there is a time interval between appearances.

 

But this is not a medical diagnosis site so I repeat the ScienceForums prescription

See your doctor.

Oooh, I hadn't thought of that! And some of those hairworms have mind-controlling toxins that can make insects do bizarre things. 

Perhaps there's a correlation between bites like these and recent bizarre human behavior. We should check for bites before letting folks vote, or when they don't want to wear a mask in public. /jest

Nah, Trumps has a new infallible strategy for reelection.

Appoint Alexander Lukashenko as campaign manager.

Could also be a skin cancer.

I will assume you've not been swimming in Lake Chad.

No expert here, but I agree with most popular advice:

See your doctor.

Hi, I am in fact a doctor. And I also have a recurring insect bite after slapping away an insect from my back 2 years ago. Every 2 months, approximately, a new sore forms at the exact spot where I was bitten and itches  and pops open. This all lasts 3-5 days. I have considerable lymphadenopathy above and below the "bite". I feel otherwise fine. I have asked multiple doctors what they think about it and no one knows or seems to ascribe it much meaning. Occasionally someone suggests it is shingles, but it never spreads, is never painful, and recurs much more often than shingles should. I think there is definitely a recurrent insect bite thing, yet it is no known in "normal" western medicine. I guess it would be liver heat rising in Chinese medicine. Please keep me up to date on other people's situations with this! It does not seem to be related to more or less stress, or anything else consistently.
