I understand...have had same problem. I got rid of the scabies with massive doses of ivermectin paste taken orally. It took month and mnths of almost daily treatment til it finally worked... You judt order the equimectrin paste for horses that is in an injectabel plastic tube to be injected into mouth of hourse..not to be injected under skin..repeat this does not go under the skin.. i started taking 125 tblsps of it to see if it would work...tried it quite a few days for few weeks..nothing. I increased it to 500 tblsps of it and then I started to see some releif.. but it has to be taken almost every day for weeeks and really two months to really knock it out and the life cycle out..otherwise it returns...the itchy cralwies will come back if u keep it up for several months as the new ones hatch. so u must continue to clean your house. floors, bed sheets change each day...throw out old deoderant and tooth brush, face comsetics, eyebrown pencils, mascara..all have been infected. start over. spary house each day with odorless feal spray with growth regular in it plust garden sprays...make sure you dont get new bits. only way to do it keep house, clothes, shoes. sockks. bedding , immaculately clean...it goes away so slowly..i think it took total of 24 tubes of equimectrin before I finally knocked it out of my body.. but bec I am afraid I might accidetally reinfect myself from somethinng here in the house i like to keep a few extra tubes around so i do maintencance like once a week or twice aweek for awhile til i am convinvced it is really gone.
