Dermatographism: You are releasing histamine from tissue. The red streaks with touching / scratching the skin = mechanical/pressure release of histamine = "dermatographism". The itchy welts = urticaria which is another type of allergic manifestation. Although it can be challenging sometimes to discover the exact trigger for this type of reaction your doctor can advise effective therapy if allergy persists.
