I have a post nasal drip so i have been taking vitamin c, andolex, acc200. is it better to try dry up the muccus or let it run so i can blow my nose?

Depends : If the problem is from a cold, you will just treat the symptoms. If this is from an allergy, a steroid nasal spray will likely work the best. Saline irrigation often helps as well.

ROOT CAUSE: Teeth and sinus being close, post-nasal drip is a common condition we discuss with our patients. Is your condition seasonal, or constant? Medical doctor's prescription is often a quick way to feel back to normal and better again. If this is from allergies, find out what causes it so you can find a safer way to address the root cause. (For instance, taking local raw honey for pollen allergy, etc.)
