Allergies Community

I need help understanding test results recently completed. I have suffered from circular raised itchy spots about the size of a nickel that last approx. 3+ days each outbreak over my body since Dec 2011, random swelling of right arm and left leg, aching joints, low grade fever, fatigue, and a rash with very tiny pustule-looking spots that sometimes merge together into larger sections. I have gone to multiple primary care physician visits, then referred to Dermatologist who subsequently referred to Allergist/Immunologist. After multiple tests, the Allergist/Immunologist has basically said that while various tests were abnormal, he is not sure what is wrong w/me, says that I'm "unusual", and has referred me back to Dermatologist. At this point, I don't know what to do and I'm not sure what type of doctor I need to go to next. Any help you can provide would be appreciated.
