mite skin infections

Postby SSSdave » Tue Aug 09, 2016 10:35 am

A day after returning from my Pine Creek backpack last Saturday, I developed familiar red bumps under my wrist watch band of my left hand and also a few on the side of my waist where my pack belt pressed. By Monday the itchy bumps on my wrist had expanded onto the upper surface of my hand. In the past I have had similar episodes every year or so after backpacking in the Sierra. One of my brothers also had these symptoms 3 decades ago. At that time he was diagnosed as having a probable mite infection and was given insecticide lotions.

The symptoms are similar to chigger (also a mite) bites that only occur east of the Rockies while the bumps and itching are not as severe and are not similar to the more common scabbies mite infections. Note chiggers typically bite in areas where clothing is tight like under a wristwatch, belt, etc that is exactly per my experience. The mite species family is large and not fully studied in all environments so it can be expected little is known about mite species in remote mountain areas. One would expect there are mites infecting rodents and deer of our Sierra Nevada so my suspicion is my symptoms are caused by one of those mites. Usually the bumps and itching lasts a week or so and then fades away. That would match some of the symptoms I've read about on their life cycle.

Am expecting some others on the board that have also backpacked a lot over the decades, may also have occasionally developed such a mystery mildly itchy rash?

nope. Did you go to the doctor or scrape yourself to look under a microscope? Doesn't sound like a nice experience though.

I can't recall having a rash like that and I am a magnet for biting insects and the like.

Guess I need to follow up with this.

A couple days later I noticed I still had a decade old tube of pyrethrum medicinal ointment so put some of that on the area of interest. Next day the itching stopped and by a few days later the red bumps had slowly mostly disappeared. May have just been coincidence or maybe the pyrethrum killed em.
