Periodically, There Is A Sweeping Skin Sensation That Feels Prickly

Periodically, there is a sweeping skin sensation that feels prickly and peeks to a point of string itchinges feeling. I have never been allergic to anything , but if would presume that is the cause. I have had it at other times and more recently typically around 2 or 3 am. Today I ate around 8pm.
