Primary Care Internist has sent me to two allergy doctors, and an ENT with no resolution. The ENT doctors here do not recognize ENS and are unwilling to address the possibility that is my problem. I have had a CT scan of my sinuses and an MRI of my head with no resolution. A second MRI/MRA was done 12/20 and I have no results for yet. Beyond that, my primary care doctor is as frustrated as I am at this point. The possibility of ENS was something that I found while researching my symptoms and he feels its a strong possibility. The problem is, there are few doctors that recognize ENS which brings us to why I was reaching out to Mayo Clinic. Can I assume that you can not refer me to a Mayo doctor that recognizes ENS?
