    Dr Barrera is great! The only reason I marked the confidence number down is because I've been struggling with the same unexplained inflammation symptoms for over a year, and we haven't been able to find the root cause. Dr Barrera has referred me to multiple specialists, including GI, Rheumatology, Neurology, Internal Medicine and ENTs and all of these doctors have also found no reasonable answers to why the situation continues. I think my confidence in any provider finding the solution to my problem is waning. However, to clarify, I have complete confidence in Dr. Barrera's ability as an endocrinologist - just starting to feel less than great about the long period of unexplained symptoms and his ability to figure out the mystery.
