Hello, I have been having what I call these itchy scalp , and skin seizures for almost a year now. They are on and off, wake me up, because this only happens at night. It makes me scratch at my head, and skin like a mad animal. I can t explain it, I have not been using anything different as far as soaps go. And they don t happen every night, just sometimes. What gives?!?! I have read on stress , lymph cancer s, allergies, etc.
