alright, I;ll give you a try. I awoke one morning to find a crown like water blister on the crown of my head, it was painful to the touch. It lasted around a week and then I started to feel a bunch of crawling things under my scalp. they were itchy as the moved about. then after about a couple of weeks they started to move down to my face and down the back of my neck and ar3e now all over my body too as well still in my scalp and face. in other words all over me now. I have seen my doctor and he has tried pills and sabie treatments with little or no success. when I try to sop them with my finger nail [ only pushing not scratching or breaking the sin] they ll often leave a watery or blood substance which turns into a scab. And they just move onto another location in area. Got any Ideas what they are and how to rid myself of them Doc ?
