I know what your going thru, I had those symptoms for 12 years. All the test also. It seemed strange to me that I would get this for a while and then it would go away, only to return at a later time. Then on one visit to the doctor, he said that I had sinus condition. Altho, I really didn't have all the symptoms. Some people don't realize they have this, if they don't have the sinus pain. Anyway, he gave me a sample of Flonase. And it worked. Worth a try?
