Hi, I was involved in a car accident 5 days ago, resulting in mainly trauma to the right side of my face, mainly my right forehead, cheek and nose. I now suspect that I may have sinusitis due to a frequently runny nose, post nasal drip, burning nose, itchy throat and last throat pain (burning) mainly in the evening until early morning.... Could this be the case? If so what should I do? It s very uncomfortable.
