Hi, I have no known allergies, 3 weeks ago I started getting itchy ankles which on certsin nights itchy enough to wake me, then I began to notice that I was breaking out in irregular shaped raised welts . This has now been ongoing for 3 weeks. The, welts appear all over my body, mainly snklesr, thighs, back and forearms. Nothing on my face or chest/abdomen. The itching us horrendous thst I scratch baiscally till I bleed.... any ideas?
