Hello, Actually i am feeling crawling like a worm(may be) in my left side brain. Its like some one touching my left side hair. The area it covers from the corner of left side forhead to left side ear(not in ear but at the top of ear). I dont have any pain. It is being from last 6 months. In begnning it happens once in a week. But now it happens every day in night approx between 10 pm to 11 pm for 4-5 minute. Please suggest me, is it any serious desease or it is any other thing.
