If you make Dr's appointment for one aliment is it ok to bring up others?

I recently moved and now have a new PCP who knows nothing about me medically. I have a family history of diabetes and am currently having trouble with my own blood sugar levels. Three weeks ago I made and appointment for the 15th of April since my doctor was apparently very backed up from his vacation. Now I have begun to develop a sinus infection with I develop every year, much to my disgust. I don't want to appear a whiner to my doctor but without antibiotics my infections can last 3 miserable months and spread to my ears. Is it considered okay to bring up more then one aliment at a doctors appointment?
