I have had the same problem for the past 6 years I have been to doctor after doctor and the doctors think I am crazy, they prescribed me seraquale if that is spelled right, i dont think it is but you get it, I have been so depressed lately because I know what I feel and it is unbareable sometimes and it is so hard on you mentally when no one understands or even cares for that matter what is wrong with me, I have been dealing with this as well as pin pricks or biting all over as well and when I look to see what is biting me I see little black specks, and I cannot get any help here in california and now my bf has the same thing as well.
