What Causes Feeling Tickling Sensation Behind Ears And In Nostrils?

Hi, I have been battling a parasite or some type of mite. I. Feel a tickling sensation behind my ears, especially in my nostrils, between my toes and like something is crawling on my legs and arms. I will see a black speck and remove it with tweezers an within a couple minutes another black speck will appear. I will shave an look a little while later an some of the hair has "grown" back. I have random wounds and lesions that appear on my body that has a hair that will grow in the middle of it an sometimes the hair is zig zagged or I will pull the hair out with tweezers and I can hold that hair close to other hair and it is like static-- it will make the other hairs move around. I've tried tee tree oil, peroxide lotions, shaving, bleach and Epsom salt (only thing that has helped but only a little. It is scaring me. It is constantly tickling or moving and I'm spending all my attention on trying to remove it. I am a past IV drug user that used meth. Thanks for any help!
