Avoiding antibiotics for a sinus infection can lead to brain abscess quite easily. Personal use of antibiotics isn't creating treatment resistant bacteria, it's animal agriculture putting them in the feed so they don't have to treat infected sores from living in close quarters.

This infection is acute. I definitely want them. I'm in agony. Last time I had antibiotics was like 8 years ago or so.

Antibiotics are extremely dangerous to use and should only be used in the most extreme situations.

"Doctors" is a pretty loose term and why they now refer to them as "Providers". An actual doctor requires about 10 years of education/training, so they came up with a new type of "doctor" called a mid-level, which is a 6 year degree. Mid-levels are almost exclusively what you see at walk-in clinics and a majority of other visits to a health clinic. Here's how mid-levels work, they have you describe your problem and then they go to a website, type in your problem, and the website tells them exactly what to do and what medication to prescribe. Without that website they are dead in the water as they don't have the training to properly diagnose and prescribe medication, only an actual doctor has that ability. You'd have to be smooth brained to think that the websites those mid-levels go to aren't heavily funded by big pharma, who have basically created a simple way to push their drugs without the bother of having actual doctors get in their way.

So antibiotics were prescribed to OP because a website funded by the people who make antibiotics prescribed OP antibiotics. You'd be much better off scouring the Internet and finding people who suffer the same symptoms and learn what cures worked for them and then experiment with those cures. Save you money, time and suffering.
