I Am In Desperate Need Of A Hip Replacement. I

I am in desperate need of a hip replacement. I was told in order to get it I have to be able to take 2 antibiotics. I have been allergic to antibiotics since I was 17 years old. I also have 4 Auto Immune Dieases. The allergy doctor has been trying to find me something, but we are not having any luck. He wants my cardiologist to take me off my bata blocker for more testing. We did that once before and all it did was create more problems. Is there some kind of specialist that really knows how to deal with someone like me ?
