First, if I feel some crawling on my scalp
and hit the spot (as like trying to
splat the bug) it will start to
crawl the other direction. I also get the same thing if I apply tea tree oil or epsom salt to the area where they are crawling, the run and move to another location.
Second, now that I feel them under my skin it really hurts when they move, I feel pain in my kneed, back, and other places.
