You said you had been working in your yard, so is it possible you're allergic to something outside? I hope you figure out what's causing your hives! I've had mine for over a year and I can't figure out why I have mine either, and believe me I've tried almost everything I can think of. Definitely get some antihistamines and see an allergist and/or Dr., although it's been my experience that Dr.'s know very little about
hives. My allergist has helped me the most. Good luck to you.
hives b gone!
