I would find another Specialist that is with a big office or hospital and keep pushing. My internal medicine Dr is great and understanding. I have been where you are with Dr's but truly there is one out there that knows how to deal with this. Have you went to an Internal medicine Dr yet? Believe it or not my ENT was the first to diagnose WG. Don't give up. Take it from someone who felt like you. It made my WG worse and in the long run, made more problems for me and several surgerys due to giving up.
