Hello, I read that you also recently had a sinus infection, which seems never to have gone away.
We are not medical professionals, and cannot give you medical advice, only share our own experiences.
However, a headache lasting 2 weeks, accompanied by other symptoms. is quite concerning. When you say it will be "a while" before you can see a doctor, are you talking about days or weeks? Also, is the headache relieved by Tylenol or other over-the-counter pain relievers?
