"it took me a year to realize that this product was causing my itchy palms.  i had hives on my palms that would flare up when i ate soy, and sometimes after touching things at the gym. after starting the nuva ring, i became very sensitive to soy allergens.  i kept trying to eliminate every trace drop of soy in my diet, but it seemed like i was more sensitive to soy everyday.  then one month, i put in a  new ring and suddenly my palms itched like a hundred fire ant bites, and i realized i was not just allergic to soy.  i was actually allergic to the nuva ring!!!!!  my soy allergy persists after quitting the nuva ring, but no more itchy palms."
