Again, your pic looks amazingly like the ones I posted when first joining the forum. After nearly 3 months, I am now thinking they are pinworm eggs/larvae. I spray them with flea spray since I can not take meds right now. If you are not killing them when you do laundry-I also spray my laundry with permethrin-and then you put "clean" clothes on, they will begin to hatch and itch. Treat your laundry and if it has been on your butt, like underwear, washcloths, or towels; pre wash those items and wash again in with anything else you have worn. Dry in high heat twice if you can afford it. Afterward I use a lint roller and double check my underwear for the tiny white specs. They keep coming though. Have had them lay and hatch in my vagina, urethra, and most recently on my thighs and belly above my pubic hair. It does seem at times as if they are coming out of my skin. Have some O&P pending so hope to find out what this is. Other than persistent that is. I mix Ivermectin horse paste in organic cocnut oil and diaper rash ointment and smear it and shove everywhere I can. It helps some but does not stop them all. Remember, if it is pinworm eggs, they can become airborne when dried and you can actually breathe them in and reinfect yourself. Get a mask and start using gloves to wipe yourself. I have gotten the amount of it down this way after much trial and error. Isolate your bathroom from other family members if you can.
