Oh my gosh, Jo An, that sounds terrifying. I will share a "sinuses" story you can probably appreciate:

I once had chronic headaches and a host of other scary neurological side effects besides, while I was taking an antibiotic. I was told that my headaches and debilitating neurological problems were stress from being a Ph.D. student and that I must, furthermore, be in denial about being depressed. I even had elevated eosinophils, which indicated some kind of allergy... but when I told the doctor that I had no known environmental allergies, she simply countered by insisting that I must have them. She gave me Allegra-D, which is a vasoconstrictor and, thus, made the headaches worse. She also kept insisting that my headaches were in my sinuses; I was 25, so I knew where my sinuses were by then and what they felt like. I told her it was definitely not my sinuses, but she didn't believe me.

Meanwhile, during that period, the cognitive and other neurological symptoms got so bad that I was told to go to an ER; I had symptoms of what resembled a stroke. Yet since no stroke was actually happening, a doctor at the hospital wanted to give me Xanax, and another told me to start drinking wine to calm myself down. I was so frustrated. I calmly pointed out that I was not suffering from anxiety and that something was genuinely wrong. They wrote me off.

It was 1 year later that I was prescribed the same antibiotic again that my symptoms came back — and a non-doctor friend pointed out that I seemed to be allergic to the antibiotic. Lo and behold, she was right.... which also explained those elevated eosinophils the previous year. The "sinus" headaches had been from increased intracranial pressure. I could have died. Or at the very least could have gone blind. But no. It was supposedly a cocktail of depression, anxiety, sinuses, and allergies to trees and flowers that I'd never had before. No matter how many times I insisted that none of these things was the correct diagnosis.

I'm glad you ultimately found a competent doctor who believed you. Such doctors shouldn't be so few and far between. Here's to hoping that whenever there's an emergency in the future, doctors worthy of their positions are on our cases.
