Wow, it sounds like you have been through the mill.
Well, in addition to the several ENT's in my area, I also saw an
ENT at Mayo Clinic. I had asked my primary care physician to refer me. I visited Mayo clinic five times in four months. During that time, I also saw many other specialist, had a needle procedure in my right face and nasal surgery. They did find a small mass behind my optic nerve, I forgot to say, I started losing sight in my left eye, too. The first procedure was for biopsy but was not conclusive. The surgery was also for biopsy and that also was not conclusive.
They believe I have an auto immune illness that they can't define. So, they started me on a auto immune medication. My case was sent to my doctor and he monitors me. After taking the auto immune medication for three months, my doctor started to ween me off the prenisone. Since January, I have gone from 60 mgs. per day down to 2.5 mgs. per day. My sight in my left eye is improving. However, for the last month, I have had significant body and muscle pain. After running many blood test, my Dr. says it is probably prenisone withdrawel. Thanks be to God, I finally started to get SOME relief this past week. I have had several massages over the last 10 days to assist with the relief. I know I will be healed soon.
Thank God, It sounds like you are having better results then I had. I hope you continue to have good results and I will pray for your healing.
