@pcjohnson - From Tinkerbell - I just talked to my neighbor. I cannot tell you which clinic is better to go to but these are some of her symptoms. Joint pain, rash, stomach pain, headaches, burning in legs and arms, total body hives. This went on for 5 years after first hip was done. She was seen in the Dermatology Department and the Allergy Department is located right next to it. She said it took her 2 weeks to get all of the testing. You have to wait 1 day between each day of testing so they can read the results off of your back. A Dr. Hall in Dermatology did the testing. She is starting to feel good and this is a few months since the surgery to replace the hip joint. Her allergy is to the cobalt. Metal testing is a specific type of testing. She would be happy to talk to you on the phone and we would have to see how this would be accomplished.
