text: what's the best way to get rid of a sinus infection without going to the doctor? i have a sinus infection and can't get to the doctor until thursday. what the best otc med? lots of saline nasal spray, like ocean brand. you may be too dry to let things drain. also try breathing in steam through the nose or use humidifier.   on the other hand, if you have lots of drainage try sudafed non-drying. for the headache part if severe, try motin/advil.  a warm towel from the microwave may help any facial pain.  drinks lots of water and be stingy on the amount of dairy, as dairy thinkens the mucus. and sleep on 2 pillows and that may keep you from getting too blocked up.  good luck to you! :) i hope you feel better real soon!
