"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."
