Hello Liz,
I am so sorry to hear that you are having chronic untreated pain. I'd like to welcome you to our Pain Management Community.
I agree that your symptoms sound like a sinusitis. What kinds of physicians have you seen? Have you had imaging done of your sinuses? If not I would request one. Sinusitis can be difficult to treat. I am prone to sinusitis and have had to have up to six weeks of ATBs to completely clear it.
We have other communities that may offer additional suggestions. I have provided the links below.

Be assertive and insist on answers. If your current PCP will not investigate your painful symptoms please don't hesitate to get a second opinion. I hope you will let is know what you discover. We'll look forward to hearing from you again soon.
Best Wishes,
